the total "cast" of a laptop computer is $1278.24 the local sales tax rate is 7.6% what is the retail price.

x = 1187.96

Step-by-step 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
