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

A.

Step-by-step 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

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
