Mrs. Peele's family went out to dinner. They spent $42.50 on dinner, 7% tax, and on top of both costs they left an 18% tip. How much total did her family pay for dinner?

 $53.13

Step-by-step explanation:

First find how much they spent on tax by multiplying 42.50 by 7%.

7% * 42.50 = 2.98    This means the tax amount was $2.98.

Next find the how much the tip was by multiplying 18% by 42.50.

18% * 42.50 = 7.65   This also means the tip was $7.65.

Now combine the cost of the dinner plus the cost of tax plus the cost of tip to find how much in total they spent.

42.50 + 7.65 + 2.98 =  53.13

the answer is a. q=6,r=6√2

step-by-step explanation:

the correct answer would be d because the slope is -2/2=1 and the y intercept is at 2 so that is the correction equation
