79.30 ---- 100%
The while store is discounted by 12% So subract 12 from 100

100-12 = 98

We have to figure out what 88% is

79.30 ---- 100%
X ------------ 88%

Cross Multiply

79.3× 88 = 100x

6978.4 = 100X

69.784 is without taxes

69.784 = 100% {100% because it is the total price.}

69.784 = 100%
X --------- 6.25%

Cross Multiply

69.784 × 6.25 = 100X
436.15 = 100 X
X = 4.3615


69.784 + 4.3615
74.15 is the answer

makvit [3.9K]

Answer:

Step-by-step explanation:

A. distribute the X to the X in the parenthesis and you get 2x. Then distribute the X to the -7 in the parenthesis and you get -7x. Combine like terms so that would be 2x-7x and you get -5x.

C. distribute the 6x to the X in the parenthesis and you get 7x. Then distribute the 6x to the 2 in parenthesis and you get 8x. Combine like terms so that would be 7x+8x and you get 15x.

E. Not sure on this one, sorry.
