Question

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

Answer 1

$120.

Step-by-step explanation:

Let x be the original price of computer.

We have been given that Val buys a computer for $920. This is 115% of what the store paid for the same computer. This means that 115% of x equals 920.

Now let us represent this information in an equation.

`(115)/(100) x=920`

`1.15x=920`

`x=(920)/(1.15)`

`x=800`

Therefore, store paid $800 for the same computer.

Now let us subtract amount paid by store from amount paid by Val for the same computer to get the profit earned by store.

`\text{Amount earned by store on the sale }=920-800`

`\text{Amount earned by store on the sale }=120`

Therefore, the store earned $120 on the sale of the computer.
