Problem 27E

Determine which transposition errors the check digit of a UPC code finds.Some airline tickets have a 15-digil identification number a1a2…a15 where a15 is a check digit that equals a1a2…a14 mod 7.

Step-by-Step Solution:
Step 1 of 3

Chapter 5—Cost Volume­Profit Relationships Primary purpose – to estimate how profits are affected by the following five factors: 1. Selling prices 2. Sales volume 3. Unit variable costs 4. Total fixed costs 5. Mix of products sold. However, to simplify calculations, three assumptions are held: 1. Selling price is constant. The price of a product or service will not change as volume changes. 2. Costs are linear and can be accurately divided into variable and fixed elements. The variable element is constant per unit. The fixed element is constant in total over the entire relevant range. 3. In multiproduct companies, the mix of products sold remains constant. Contribution margin – the amount remaining from sales revenue after variable expenses have been deducted. Break­even point – the level of sales at which profit is zero. Concept Check: 1. Which of the following statements is a common assumption underlying cost­volume profit analysis a. The variable cost per unit remains constant. b. The selling price per unit remains constant. c. Total fixed costs are constant within the relevant range. d. The total variable costs remain constant as the level of sales fluctuates. 2. One a company hits its break­even point, net operating income will a. Increase by an amount equal to the selling price per unit multiplied by the number of units sold above the break­even point. b. Increase by an amount equal to the contributi
