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 =  w 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 = 270 pounds. (a) What single bench press weight M corresponds to 9 repetitions of this weight? (Round your answer to two decimal places.) M =  lb (b) What number of repetitions n of this weight corresponds to a single bench press of 277.72 pounds? (Round your answer to the nearest whole number.) n =  repetitions
