Find each percent of change. Round to the nearest percent if necessary. State whether the percent of change is an increase or a decrease. 1. 30 inches to 24 inches

2. $126 to $150

1. 20% decrease

2. 16% increase

Explaination:

Question 1.

30 inches to 24 inches is a decrease, because 24 is smaller than 30.

(30-24)/30 * 100%

= 6/30 * 100%

= 20%

Ans: 20% decrease

Question 2.

$126 to $150 is an increase, because 150 is larger than 126.

(150-126)/150 * 100%

= 24/150 * 100%

= 4/25 * 100%

= 16%

Ans: 16% increase
