I need help with this.

The function h(a) = 0.9(200 a) is used to calculate the handicap for a bowler (a bowling handicap is a percentage of the difference between your average and a basis average). In the function h(a) = 0.9(200 a) , a bowler's average a is used to determine their handicap h . How can we undo this original function to express a new function that tells us a bowler's average at based on their handicap h ?
