Veronika [31]
Question: An aquarium is on sale for $59.50. If this price represents a 15% discount from the original price, what is the original price? 

First, you multiply the sale price and the 15% discount

$59.50*.15 = [tex]$8.92 [/tex] (To change the percent to a decimal, you take out the percentage sign and divide by 100)

Now add $59.50 to $8.92

59.50+8.92=$68.43

Answer:

$68.43 (when rounded to the nearest cent)
or
$68 (when rounded to the nearest dollar)
or
$70 (when rounded to the nearest ten dollar)
