Write an algebraic expression to represent the cost of m gallons of gasoline if each gallon costs $1.45

Is this right M-$1.45
Answered by Ms. Sue
No.

Why would you subtract?

If one gallon costs 1.45, what does 2 gallons cost? How do you know?

Answered by Gio
Two gallons cost $2.90. You have to add
