Bill paid $35.99 in tax on a laptop that cost $449.99. about what percent sales tax did bill pay

Bill paid about 7% sales tax.

Step-by-step explanation:

First, to find the value of 1%, I divided $449.99 by 100, which gave me 4.4999. I then divided the amount paid for tax by the value of 1%. That;s $35.99 ÷ $4.4999 = 7.199439887977596. Obviously, you can't put that in your math homework, plus the question says "about," so you're going to round. Because the first number after the decimal point is less than five, you round down. Therefore, the sales tax is about 7%.
