THANK YOU VERY MUCH!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 1.07xOk??If the total you pay for the vehicle, including tax, is \$13,888.60, then1.07x = 13888.60
