Question

Sandi needs three times as much paint on the outside of her boat as she needs for the inside. She has painted the outside with 18 gallons. How much paint does she need for the inside?

Answer 1

3x=18

Answer 2

solve fer x

Answer 3

If the inside of the boat is represented by x, then 3 times as much would be 3x. you're given a total of 18 gallons, so to figure out how much she needs for the inside of the boat,x, we'd solve our equation as so:

3x = 18

x = 18/3 <= tells us how much left over paint Sandi can use for the inside of her boat.
