Grace bought a refrigerator through an interest free payment plan. the refrigerator was $750 and her payments were $150 each. what percent of the total cost are the payments?

20%

Step-by-step explanation:

To do this, we need to divide 750 by 150:

750 ÷ 150 = 5

Then we divide 100 by this number:

100 ÷ 5 = 20

So the percent of the payments are 20%

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
