The sale price for a bicycle is $89.90.the sale price includes a discount of 20%.what is the original price of the bicycle

Answer 1

Set up a proportion

$89.90\ original price • 20\ 100

$89.90 • 20 = 1798
Then divide
1798 \ 100 = 17.98

Now add the 17.98 to the sale price and you get the original price of $107.88
