Brzycki's 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 = 1.0278 – 0.0278n It applies for up to n = 10 repetitions. In this exercise we consider a weight lifter who bench-presses several repetitions of w = 285 pounds. (a) What single bench press weight M corresponds to 5 repetitions of this weight? (Round your answer to two decimal places.) M = Ib (b) What number of repetitions n of this weight corresponds to a single bench press of 293.15 pounds? (Round your answer to the nearest whole number.) n = repetitions
