Carlos bought 2 packs of spearmint gum for $1.50 each and 3 packs of cool ice gum for $1.50 each. He wrote the expression 2 + 3 X 1.50 to find his total cost of the gum. Which expression should he actually use to find the total cost of the gum?

• 2+(3 X 1.50)

• His expression does NOT have a mistake. His expression WILL find the total cost of the gum.

• (3 + 2) X 1.50

• 3 X 2 X 1.50
