Below are sample questions representative of the exercises included on this worksheet and related 6.18 Solve Percent Change Problems skill assessments:

Problem 1Difficulty: Mastery

A club’s attendance rose from 36 people to 48 people. Which choice correctly calculates the percent increase and uses the correct original amount?

A25% increase because 12 divided by 48 equals 0.25

B33.33% (repeating) increase because 12 divided by 48 equals 0.25

C25% increase because 12 divided by 36 equals 0.333...

D33.33% (repeating) increase because 12 divided by 36 equals 0.333...

Solution & Explanation:Increase is 48 − 36 = 12. Divide by the original 36: 12 ÷ 36 = 0.333..., which is a 33.33% (repeating) increase.

Problem 2Difficulty: Mastery

A store claims: “We reduced the price from $120 to $90, a 33.33% (repeating) decrease.” Which choice is correct?

AThe claim is correct: it is a 33.33% (repeating) decrease.

BThe claim is correct: it is a 25% decrease.

CThe claim is incorrect: it is a 33.33% (repeating) increase.

DThe claim is incorrect: it is a 25% decrease because 30 divided by 120 equals 0.25.

Solution & Explanation:The decrease is 120 − 90 = 30. Divide by the original 120: 30 ÷ 120 = 0.25, which is a 25% decrease, not 33.33% (repeating).
