Answer:

x = 1187.96

Explanation:

Let x = price before tax

tax = x* 7.6%

tax = .076x

The cost of the computer is price before tax plus tax

cost = x + .076x

cost = 1.076x

1278.24 = 1.076x

Divide each side by 1.076

1278.24/1.076 = 1.076x/1.076

x=1187.9553

Rounding to the nearest cent

x = 1187.96

… I hope this help you
