Question

The PTA at Middletown High School is having its annual dinner and auction to raise money for music and art programs. Last year, the event raised $20,800. This year, it raised $31,408. What is the percent of increase in the amount raised?

Answer 1

51%

Explanation:

31,408-20,800=10,608÷20,800=0.51×100=51.

You subtract the retail price from the original and you divide the number you get by the original price and then times the number by a hundred.
