Change −7 10 −7 −7 10 −14 −14 −14 10 10
She writes the sum of the ten integers, then factors her expression.

She correctly determines the total change for the 10 months.

What factored expression does she write, and what is her answer?

Enter your answer by filling in the boxes.

$$

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
