HELP ME WILL MARK BRIANLEST Molly and Maddie are clothes shopping. Molly has $100.00 and a coupon for a $5.00 discount at a clothing store where each shirt costs $15.00. 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

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.

give the guy under me the 5 stare and a thanks this is his answer

A child is hopping along a sidewalk. The ratio table below shows the comparison between the number of hops and the distance traveled. Hopping Number of hops Distance traveled (ft)
20 30
50 75
80 120
120 ? Which statement correctly explains how to find the distance traveled after 120 hops? Subtract 120 – 75 to get 45, then add that number to 120. Add 30 + 75 + 120. 20 multiplied by 6 is 120, so you can multiply 30 times 6 to find the distance. 30 multiplied by 4 is 120, so you can multiply 20 times 4 to find the distance.
