Nine and one-half less than four and one-half times a number is greater than 62.5. Which of the following represents the solution set of this problem?

The answer is x>16

Nine and one-half less than is - 9 1/2 = - 9.5

Four and one-half times a number is 4 1/2 x = 4.5x

Thus, n ine and one-half less than four and one-half times a number is greater than 62.5 is

-9 1/2 + 4 1/2x > 62.5

-9.5 + 4.5x > 62.5

4.5x > 62.5 + 9.5

4.5x > 72

x > 72 / 4.5

x > 16
