Question

Mrs.D. gives 13 % of her salary to a charity. Last year she donated to the charity $6500.00. How much money did Mrs.D. earn last year?

Answer 1

Let x = Mrs. D's salary last year

13% = 13/100 = 0.13

6500 is 13 percent of Mrs. D's salary, so:

0.13(x) = 6500

0.13(x)/0.13 = 6500/0.13

x = 50,000

Mrs. D's salary last year was 50,000 dollars.
