A baseball coach would like to be able to predict number of hits his players will get based on the number of times they are at bat. He graphs some data and determines the line of best fit. The equation of the line of best fit is y = 0.32x - 20.51, where x is the number of times at bat and y is the number of hits. How many hits should he expect from a player who is at bat 157 times? Round the answe to the nearest whole number
