the price of a computer including tax was 842.50 . the sales tax was 8%. what was the original price of the computer

The original price was 780.09

Step-by-step explanation:

Let x be the price of the computer

The sales tax is x* .08

The total price is x + .08x = 1.08x

This is equal to 842.50

1.08x = 842.50

Divide each side by 1.08

1.08x/1.08=842.50/1.08

x =780.09

The original price was 780.09
