$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.  

Therefore, store paid $800 for the same computer.
