The sale price for a bicycle is $315 dollars. the original price was first discounted by 50% and then discounted an additional 10%. find the original price of the bicycle.

$787.5

Step-by-step explanation:

Let the original price of the bicycle be $x.

If the original price was first discounted by 50% and then discounted an additional 10%, the total percentage discount will be 60%.

Using the formula

S = p(1-r) where

S is the sales price of the bicycle

p is the original price of the bicycle

r is the percentage discount

Given sales price = $315

Total percentage discount = 60% = 0.6

Substituting this in the formula above we have:

$315 = p(1-0.6)

$315 = 0.4p

P = $315/0.4

P = $787.5

The original price of the bicycle = $787.5
