Question

Laney buys a t-shirt and pair of jeans for $39.93. She has a coupon that will allow her to save 15% What

will the final purchase price be after a 7% sales tax?

Answer 1

$36.33

Explanation:

So, when finding the percentage of a number you move the decimal point to the left two times.

39.93 x .15 = 6

39.93 - 6 = 33.93

(I subtracted the 6 because it was what was taken off by the coupon)

33.93 x .07 = 2.4

33.93 + 2.4 = 36.33

(Again, I added the 2.4 because it was what was added on by the sales tax)

I hope this helps! :)
