Question

A video, originally priced at $15, is on sale for $5.50. What is the percent of decrease rounded to the nearest whole number?

Answer 1

I think my answer is %10

Answer 2

Step one: Subtract $15 - $5.50 = $9.50
Step two: divide $9.50 ÷ $15 = .633 (rounded)
Step three: Multiply .633 * 100 to change it to a percent. It becomes 63.3% (rounded)
The decrease is 63.33%

Proof: $15 * .63333 = $9.50
Subtract $15 - $9.50 = $5.50
