Question

In 1990, a radio costs $25. Now, the radio costs $5. What is the percent of change?

Answer 1

80% decrease

Explanation:

take the difference between the two prices and divide it by the original price, then multiply by 100 (to make it a %)

(25-5) / 25

= 20/25

= .8 x 100

= 80% decrease

Answer 2

20%

Explanation:

`(5)/(25) =(1)/(5)=0.2=20`%
