ollegr [7]

Answer: 7.2$

hope it helps :)

step-by-step explanation:

Cost of each box = 3$

Cost of 3 boxes without 20% coupon = 9$

With 20% off Coupon = 9 by 100 multiplied by 20

                                     (the zero's cut with each other leaving)

                                     = 9 by 10 multiplied by 2

                                     (9 multiplied by 2 = 18)

                                     = 18 by 10

                                     (18 divided by 10 = 1.8)

                                     = the 20% of 9$ is equal to 1.8

                                        when subtracted with the total cost leaves 7.2$

Select the choice that translates the following verbal phrase correctly to algebra:
maria [59]

w + 15 since increased by 15 means add on

12y + 11 since product of 12 and y means multiply 12 and y = 12y

one half n - 16 since one half of n and decreased by 1 6 , subtract 16

2b - 6 since Corinne is 6 years younger represented by b - 6

sum of their ages = b + b - 6 = 2b - 6

9h + 40

$ 9 per hour for h hours = 9 × h = 9h plus the $ 40 from carpool
