Question

Sara owns a used furniture store. She bought a chest for 42$ and sold it for 73.50. What percent did she mark up the chest?

Answer 1

75%

Explanation:

We are given that Sara bought a chest for $42, and then sold it for $73.50.

Recall that when finding by how much something was marked up, you should use the following formula:

(new price-original price)/(original price)

Let's substitute the values, like so:

`(73.50-42)/(42)=\\\\ (31.50)/(42)`

Now, set up a proportion to find what this fraction is as a percentage:

`(31.5)/(42) =(x)/(100) =\\42x=3150=\\x=75`

So, the price was marked up by 75%.
