Molly thinks that she can buy 8 shirts, but Maddie says that Molly can buy 7 shirts. The equations they used to model the problem are listed below.

Solve each equation algebraically, justify your steps, and determine who is correct and why.

Molly's equation
15x + 10 = 100

Maddie's equation
15x - 10 = 100

Answer 1

Molly's equation

15x + 10 = 100

-10 -10

15x=90

/15 /15

x=6

Maddie's equation

15x - 10 = 100

+10 +10

15x=110

/15 /15

x=7 1/3

MADDIE IS RIGHT

this is because she said 7 ans=d you cannot buy 1/3 of a shirt.
