Question

Coocjies cost $1.50 each and gallons of milk cost $6.00 each.Grover plans to buy 8 cookies.If he can spend no more $30,gow many cartons of milk can he buy?​

Answer 1

He can buy no more than 3 gallons

Explanation:

Let c = cookies and m = milk

1.5c + 6m

This is how much he is going to spend

it must be less than or equal to 30

1.5c + 6m≤ 30

He is going to buy 8 cookies

1.5*8 + 6m≤ 30

12 + 6m ≤ 30

Subtract 12 from each side

12+6m -12 ≤ 30-12

6m ≤ 18

Divide by 6

6m/6 ≤ 18/6

m≤ 3
