Solve the problem.

Sales of frozen pizza for a club fundraiser increased from 500 one year to 665 the next year. What was the percent increase?

75.2%

24.8%

67%

33%

33%

Step-by-step explanation:

Let's find the answer by using the following formula:

(final amount) = (initial amount) + ((initial amount) * (percent increase)) so:

665=500 + (500*X) where X=percent increase

Solving, we have:

X = (665-500) / 500

X=0.33=33%

In conclusion, the percent increase was 33%.
