Question

Tony bought a shirt for a friend's birthday for $27.00. He liked the shirt so much that he returned to the store a week later to buy a shirt for himself. Tony found the price of the shirt had changed to $32.13. Rounded to the nearest whole percent, what is the percent increase in the price of the shirt?

Answer 1

You have to divide 27 by 100 and that gives you .27.

If you multiply until you reach 32.13 with different numbers you get 19. It is a 19% increase.
