Dale saw that the campus bookstore is having aspecialon padsof computation papernormally pricedat $3 a pad, now on sale for $2.50 a pad. This saleis unusual and Dale assumes the paper will not beput on sale again. On the other hand, Dale expects that there will be no increase in the $3 regular price,even though the inflation rate is 2% every 3 months.Dale believes that competition in the paper indus-try will keep wholesale and retail prices constant.He uses a pad of computation paper every 3 months.Dale considers 19.25% a suitable minimum attrac-tive rate of return. Dale will buy one pad of paperfor his immediate needs. How many extra pads ofcomputation paper should he buy?

Assume that hismarginal personal income tax rate is 34% forfederal and state taxes.(b)Now assume there is 7% per year inflation, com- pounded annually. Sam will increase the rent 7%per year to match the inflation rate, so that afterconsidering increased taxes and other expenses,the annual net income will go up 7% per year.Assume Sams marginal income tax rate remainsat 34% for all ordinary taxable income related tothe property. The value of the property is nowprojected to increase from its present $85,000 ata rate of 10% per year, compounded annually.If the property is sold after 5 years, computethe rate of return on the after-tax cash flow inactual dollars. Also compute the rate of return onthe after-tax cash flow in Year-0 dollars.

A small researchdevicecan bepurchasedfor $10,000and depreciated by MACRS depreciation. The netbenefits from the device, before deducting depre-ciation, are $2000 at the end of the first year andincreasing $1000 per year after that (second yearequals $3000, third year equals $4000, etc.), until thedevice is hauled to the junkyard at the end of 7 years.During the 7-year period there will be an inflation ratefof 7%.This profitable corporation has a 40% combinedfederal and state income tax rate. If it requires a real12% after-tax rate of return on its investment, shouldthe device be purchased?

A couple in Ruston, Louisiana, must decide whetherit is more economical to buy a home or to con- tinue to rent during an inflationary period.The couplerents a one-bedroom duplex for $450 a month plus$139 a month in basic utilities (heating and cooling).These costs have a projected inflation rate of 5%, sothe couples monthly costs per year over a 10-yearplanning horizon are:n=12345678910Rent 450 473 496 521 547 574 603 633 665 698Utilities 139 146 153 161 169 177 186 196 205 216 The couple would like to buy a home thatcosts $75,000. A local mortgage company will pro-vide a loan that requires a down payment of 5%plus estimated closing costs of 1% cash. The cou-ple prefers a 30-year fixed-rate mortgage with an 8%interest rate. The couple falls in the 30% marginalincome tax rate (federal plus state), and as such, buy-ing a home will provide them some tax write-off.It is estimated that the basic utilities for the homeinflating at 5% will cost $160 per month; insuranceand maintenance also inflating at 5% will cost $50per month. The home will appreciate in value about6% per year. Assuming a nominal interest rate of15.5%, which alternative should the couple select?Use a present worth analysis. (Note:Realtors salescommission here is 5%.

When there is little or no inflation, a homeowner canexpect to rent an unfurnished home for 12% of itsmarket value. About1/8of the rental income is paidout for property taxes, insurance, and other operatingexpenses.Thus the net annual income to the owner is10.5% of the market value. Since prices are relativelystable, the future selling price of the property oftenequals the original price paid by the owner.For a $150,000 property (where the land is esti-mated at $46,500 of the $150,000), compute theafter-tax rate of return, assuming the selling price59 months later (in December) equals the originalpurchase price. Use modified accelerated cost rec-overy systemdepreciationbeginning January1.Also,assume a 35% income tax rate.

(This continues Problem 14-83.) As inflation hasincreased throughout the world, the rental income ofhomes has decreased and a net annual rental incomeof 8% of the market value is common. On the otherhand, the market value of homes tends to rise about2% per year more than the inflation rate. As a result,both annual net rental income, and the resale valueof the property rise faster than the inflation rate.Consider the following situation.A $150,000 property (with the house valued at$103,500 and the land at $46,500) is purchased forcash in Year 0. The market value of the propertyincreases at a 12% annual rate. The annual rentalincome is 8% of the beginning-of-year market valueof the property. Thus the rental income also increaseseach year. The general inflation ratefis 10%.The individual who purchased the property hasan average income tax rate of 35% (a)Use MACRS depreciation, beginning January 1,to compute the actual dollar after-tax rate ofreturn for the owner, assuming he sells the prop-erty 59 months later (in December). b)Similarly, compute the after-tax rate of return forthe owner, after taking the general inflation rateinto account, assuming he sells the property 59months later. b)Similarly, compute the after-tax rate of return forthe owner, after taking the general inflation rateinto account, assuming he sells the property 59months later.

Consider two mutually exclusive alternatives statedin Year-0 dollars. Both alternatives have a 3-year lifewith no salvage value. Assume the annual inflationrate is 5%, an income tax rate of 25%, and straight-line depreciation. The minimum attractive rate ofreturn (MARR) is 7%. Use rate of return analysis todetermine which alternative is preferable.YearAB0$420$300200 1502 200 1503 200 150

The purchase of a large-volume copier is being con-sidered. Use MACRS and the current tax law. Thecorporations taxableincomeexceeds$20M.Thefirstcost is $18,000. Maintenance cost per year is $1300in Year-1 dollars. The salvage value after 10 yearsis $2000 in Year-10 dollars. Assume the real MARRis 8%, and the inflation rate is 5%. Find the equiva-lent annualcost after taxes. Does inflation increase ordecrease the annual cost?

Ruralville is suffering a 1% annual loss of popula-tion and property values. Even so, Ruralville mustmaintain its tax collections at a constant value of $3.2million. If the inflation rate is 4.5%, what inflationrate in taxes for the remaining taxpayers is requiredfor Ruralville to attain its goal? (Note: AlthoughRuralville uses a rate of 6% for discountingpurposes,that rate is irrelevant to this problem.)
