Question

Keelah's clothing store bicycles for $50 and then sells them for $80 what is the percent of markup on the price of the coat

Answer 1

62.5%

Explanation:

We can write a proportion. We know that $50 is the original value and $80 is the marked up price. We don't know the marked up percentage. Let's call it x. We write equal ratios of
`(x)/(100)` comparing percent and
`(50)/(80)` comparing the 50 to the marked up price. We then set them equal.

`(x)/(100) =(50)/(80)`

We then cross multiply across the equal sign from numerator to the opposite numerator.

80(x)=50(100)

80x=5000

We divide to find x.

x=62.5

This means the bicycles are marked up 62.5% and the original value is 37.5%.
