Question

Stacy and Melissa work as waitresses. They both earn $7.75 per hour, plus tips. Last weekend, Stacy worked x number of hours and earned $153.95 in tips. Melissa worked y number of hours and earned $129.02 in tips. Stacy determined that using the expression 7.75x + 153.95 + 7.75y + 129.02 will calculate the amount the girls earned together last weekend. Select another expression the girls could also use.

A
7.75x+y+282.97

B
7.75(x+y)+282.97

C
7.75(xy)+282.97

D
7.75x+7.75y−282.97

Answer 1

B - 7.75(x+y)+282.97

Explanation:

7.75x + 7.75y is the same as distributing 7.75 to x + y. 153.95+129.02 also is equivalent to 282.97, so B should be the answer. The other answers either don't have enough steps or the wrong operation.

hope this helped!! <3
