Ok...if the sales tax is 7%, then you will pay 7% of the purchase price for tax.

If the purchase price is x dollars, the sales tax will be 7% of x, or 0.07x.

The total you will pay on a purchase of x dollars is x + 0.07x....or,
1x + 0.07x, or 1.07x

Ok??

If the total you pay for the vehicle, including tax, is $13,888.60, then

1.07x = 13888.60

i set up the problem like

The price of car = X

tax on car = 0.07 * X

X + 0.07 * X = 13,888.60

1.07 * X = 13888.60


but when i solve it the answer are total wrong~ can someone please tell me what part did i miss? also if anyone knows any tips on solving word problems please tell me. THANK YOU VERY MUCH!
