The sale rack at the department store said that an additional 30 percent discount would be taken on all items. if a dress on the sale rack had an original price of $86 and was already marked down by 25 percent, what is final cost of the dress before taxes?

I think it's $45.15

$47.30

Explanation:

86* .55 (25+30 discount) = 47.3

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
