Question

I'm supposed to answer this word problem "Martin bought a television for $225. It had been on sale for 25% off. How much money did Martin save on the television because of the sale?" I want to know what equation I have to do to get the answer since I have to "show my work" I don't want an answer to the problem I just want an equation for the problem

Answer 1

Martin saved $75 on the television because of the sale

Explanation:

Equations

Let's call x=the original price of the television (before discount).

The television had been on sale for 25% off, this means the discount was:

25% of x =
`(25)/(100).x` = 0.25x

The sale price was the original price minus the discount:

x - 0.25x = 0.75x

This is what Martin paid, thus:

0.75x = 225

Dividing by 0.75:

x = 225 / 0.75

x = $300

The original price of the television was $300, and the discount was:

0.25*$300 = $75

Martin saved $75 on the television because of the sale
