Question

Eric bought a new computer printer online for $150. The shipping cost was 8% of the purchase price. How much was the shipping cost?

Answer 1

$12

Explanation:

Method 1

8% = 8/100 = 0.08

Therefore, to find 8% of the purchase price, multiply 0.08 by $150:

$150 x 0.08 = $12

Method 2

$150 is 100% of the purchase price, so to find 8%, divide $150 by 100 to give the equivalent of 1% and then multiply that by 8 to find 8%:

150 ÷ 100 = 1.5 ⇒ $1.50 is 1% of the purchase price

1.50 x 8 = 12 ⇒ $12 is 8% of the purchase price
