Below are sample questions representative of the exercises included on this worksheet and related 7.25 Percent increase and percent decrease skill assessments:

Problem 1Difficulty: Mastery

After a 12.5% decrease, a school has 350 students in 7th grade. Then 14 students transfer in. What is the overall percent change from the original number and the final number of students? Round the overall percent change to the nearest tenth of a percent.

A4.0% increase; 364 students

B18.9% increase; 364 students

C9.0% increase; 364 students

D9.0% decrease; 364 students

Solution & Explanation:First find the original value by undoing the first percent change. Original = 350 ÷ 0.88 = 400. Then add 14: 350 → 364. Final value = 364. Overall percent change = (final − original) ÷ original × 100 = (364 − 400) ÷ 400 × 100 = -9%. Rounded, that is 9.0% decrease.

Problem 2Difficulty: Mastery

A store raised a calculator price by 10% to $33.00. Then it raised it again by 10%. What is the overall percent change from the original price and the final price? Round the overall percent change to the nearest tenth of a percent.

A10.0% increase; $36.30

B22.2% increase; $36.30

C21.0% increase; $36.30

D21.0% decrease; $36.30

Solution & Explanation:First find the original value by undoing the first percent change. Original = 33 ÷ 1.1 = $30.00. Then apply 10.0% increase: $33.00 → $36.30. Final value = $36.30. Overall percent change = (final − original) ÷ original × 100 = (36.3 − 30) ÷ 30 × 100 = 21%. Rounded, that is 21.0% increase.

Problem 3Difficulty: Mastery

After a 25% discount, a jacket costs $150.00. Then sales tax of 8% is added. What is the overall percent change from the original price and the final cost? Round the overall percent change to the nearest tenth of a percent.

A8.0% increase; $162.00

B19.0% decrease; $162.00

C44.0% increase; $162.00

D19.0% increase; $162.00

Solution & Explanation:First find the original value by undoing the first percent change. Original = 150 ÷ 0.75 = $200.00. Then apply 8.0% increase: $150.00 → $162.00. Final value = $162.00. Overall percent change = (final − original) ÷ original × 100 = (162 − 200) ÷ 200 × 100 = -19%. Rounded, that is 19.0% decrease.
