Question

You want to buy a calculator at $89.99, a backpack at $39.59, and a binder at $4.19. At the register, you learn that

there is a discount of 15% with no sales tax on school supplies. Which equation(s) can you use to determine how
much you will save? Select all that apply.
0.15(89.99 + 39.59 +4.19) =
1.15(89.99 + 39.59 +4.19) =
(89.99 + 39.59 +4.19) - 15 = 8
(89.99 + 39.59 +4.19) - 0.85(89.99 + 39.59 +4.19) = s
(89.99 + 39.59 + 4.19) - 0.15(89.99 + 39.59 +4.19) = 8

Answer 1

A.

Explanation:

you add all prices together and then mulitplied by the 15%. that gives you 20.0655 so you subtract that from the total price so 133.77-20.0655 and get 113.7045 or 113.70 which is the final price you pay
