Question

Hoverboards are approximately $300. Noelle had a coupon for 15% off. What is the discount Noelle will receive? Please give answer and show work

Answer 1

The question is asking what is 15% of $300.
"of" means multiply, and 15% is the same as 0.15 (% means divide by 100), so you have 
0.15 * $300 = $45.
