Answer:
Step-by-step explanation:
1) $399 = 84% of the original amount
Divide both sides by 84 to get what one percent would be
$4.75 = 1%
Then multiply both sides to get one hundred percent [the original price]
$475 =100%
Use this method to do the second question
$450.50 = 85%
Divide by 85
$5.30 = 1%
Multiply by 100
$530 = original price
