Chapter 3, Problem 46RE
General Interest
46. Studying Ty Olden is trying to allocate his study time this weekend. He can spend time working with either his math tutor or his accounting tutor to prepare for exams in both classes the following Monday. His math tutor charges $20 per hour, and his accounting tutor charges $40 per hour. He has $220 to spend on tutoring. Each hour that he spends working with his math tutor requires 1 aspirin and 1 hour of sleep to recover, while each hour he spends with his accounting tutor requires 1/2 aspirin and 3 hours of sleep. The maximum dosage of aspirin that he can safely take during his study time is 8 tablets, and he can only afford 15 hours of sleep this weekend. He expects that each hour with his math tutor will increase his score on the math exam by 3 points, while each hour with his accounting tutor will increase his score on the accounting exam by 5 points. How many hours should he spend with each tutor in order to maximize the number of points he will get on the two tests combined?

- Finance To expand its clothing line, a small corporation borrowed $775,000 from three different lenders. The money was borrowed at 8,9and10, simple interest. How much was borrowed at each rate when the annual interest owed was $67,500 and the amount borrowed at 8 was four times the amount borrowed at 10 ?arrow_forwardSales Strategy A small business is considering hiring a new sales representative sales rep to market its product in a nearby city. Two pay scales are under consideration. Pay Scale 1 Pay the sales rep a base yearly salary of 10, 000 plus a commission of 8 of total yearly sales. Pay Scale 2 Pay the sales rep a base yearly salary of 13, 000 plus a commission of 6 of total yearly sales. a. For each of the pay scales above, use a formula to express the total yearly earnings for the sales rep as a function of total yearly sales. Be sure to identify clearly what the letters that you use mean. b. What amount of total yearly sales would result in the same total yearly earnings for the sales rep no matter which of the two pay scales is used? c. On the same screen, plot the graphs of the functions you made in part a. Copy the picture onto the paper you turn in. Be sure to label the horizontal and vertical axes, and be sure your picture includes the number you found in part b. d. If you were a sales rep negotiating for the new position, under what conditions would you prefer pay scale 1? Under what conditions would you prefer pay scale 2?arrow_forward
