Question 365990
elka pays 1187.20 for a computer.
price includes 6% sales tax.


x = cost of the computer
t = tax
p = price elka payed.


p = x + t*x


1187.20 = x + .06*x


combine like terms to get:


1187.20 = 1.06*x


divide both sides of the equation by 1.06 to get:


1187.20 / 1.06 = x = 1120


price of the computer is equal to 1120.


add 6% sales tax to that and you get 1120 + 67.2 = 1187.2
