Problem 4.49

Western Refining purchased a model MTVS peristalticpump for injecting antiscalant at its nanofiltrationwater conditioning plant. The cost of thepump was $1200. If the chemical cost is $11 perday, determine the equivalent cost per month (pumpplus chemicals) at an interest rate of 1% per month.Assume 30 days per month and a 4-year pump life.

Step-by-Step Solution:
Step 1 of 3

Definitionb 1.1. Given two integers a and d with d non-zero, we say that d divides a (written d | a) if there is an integer c with a = cd. If no such integer exists, so d does not divide a, we write d - a. If d divides a, we say that d is a divisor of a. Proposition 1.2.1: Assume that a, b, and c are integers. If a | b and b | c, then a | c. Proposition 1.3. Assume that a, b, d, x, and y are integers. If d | a and d | b then d | ax + by. Corollary 1.4. Assume that a, b, and d are integers. If d | a and d | b, then d | a + b and d | a − b. Prime: A prime number is an integer p ≥ 2 whose only divisors are 1 and p. A composite number is an integer n ≥ 2 that is not prime. Ex: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29. The Division Algorithm: Let a and b be integers with b > 0. Then there exist
