Question

Val buys a computer for $920. If this is 115% of what the store paid for the same computer, how much did the store earn on the sale?

Answer 1

Hi!

We will solve this using rations, like this:

$920 equals to 115% = 1,15

$x equals to 100% = 1

_______________________

x = (920*1)/1,15

x = 920/1,15

x = 800

Store earned 15%, or in this case 920 - 800 = $120.

Hope this helps!
