Question 176199: In bowling a handicap is a change in score to adjust for
differences in players’ abilities. You belong to a bowling league in which each
bowler’s handicap h is determined by his or her average a using this formula:
h = 0.9(200 - a)
(If the bowler’s average is over 200, the handicap is 0.) Find the inverse of the
function. Then find your average if your handicap is 27.

Just solve the function for a:

h+=+0.9%28200+-+a%29

Divide by 0.9

h%2F0.9+=+200+-+a

Add -200 to both sides:

h%2F0.9+-+200+=+-a

Multiply by -1:

-h%2F0.9+%2B+200+=+a

200+-+h%2F0.9+=+a

a+=+200+-+h%2F0.9

Now just put 27 in place of h and do the arithmetic.
