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

Answer:

$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.  

$\frac{115}{100} x=920$

$1.15x=920$

$x=\frac{920}{1.15}$

$x=800$  

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.
