Question

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

Answer 1

Assuming that's 10% off the discounted price,

`x times (1-50/100) times (1 - 10/100) = $315 quad`

`x = $315 / { (.5)(.9)} = $700`

Explanation:

Check: `700 times .5 times .9 = 315 quad sqrt`
