Question

The audio store normally sells a pair of speakers for $280. They are on sale this weekend for $224. What is the percent of decrease in price?

Answer 1

Answer: 20%

Explanation:

1. Turn it into a fraction (224/280)

2. Divide the numerator (224) by the denominator (280). (224÷280=0.8)

3. Subtract 1 by 0.8 (or 100% by 80%) that should give you the answer 0.2 (20%)

Checking work:

280x0.2=56

280-56=224
