Textbook Question
Chapter 8.5, Problem 44PE
For Exercises 41-58, use a variation model to solve for the unknown value. (See Examples 4-6.)
Some body-builders claim that, within safe limits, the number of repetitions that a person can complete on a given weight-lifting exercise is inversely proportional to the amount of weight lifted. Roxanne can bench press 45 lb for 15 repetitions.
a. How many repetitions can Roxanne bench with 60 lb of weight?
b. How many repetitions can Roxanne bench with 75 lb of weight?
c. How many repetitions can Roxanne bench with 100 lb of weight?
