Question

Usual computer price is $1187.20 with 6% sales tax. What is the price of only the computer?

Answer 1

If the total cost including the tax is 1187.2, then that equals 106 percent of the price of the computer (because it is 100 percent of the price plus 6 percent of the price.)

So just divide 1187.2 by 1.06

Answer 2

Simple math.  Set it up as a proportion.

X/1=1187.2/1.06

Cross multiply

1187.2 (1) = 1.06X

Solve for X:

1187.2 /1.06 =X
