Weight Lifting Brzyckis formula is used by weight lifters to determine the weight M that is equivalent in a single repetition to n repetitions of a weight w. the formula is M=w1.02780.278n. It applies for up to n=10 repetitions. In this exercise, we consider a weight lifter who bench-presses several repetitions of w=240 pounds. a. What single bench-press weight M corresponds to 5 repetitions of this weight? b. What number of repetitions of this weight corresponds to a single bench press of 278.75 pounds?

Insurance copayment Carrie had to have 5 fillings done. Each filling cost $80. Her dental insurance required her to pay 20% of the cost as a copay. Calculate Carrie’s copay: (a) First, by multiplying 0.20 by 80 to find her copay for each filling and then multiplying your answer by 5 to find her total copay for 5 fillings. (b) Next, by multiplying [5(0.20)](80) (c) Which of the properties of real numbers says that your answers to parts (a), where you multiplied 5[(0.20)(80)] and (b), where you multiplied [5(0.20)](80), should be equal?
