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
No.
Why would you subtract?
If one gallon costs 1.45, what does 2 gallons cost? How do you know?
Two gallons cost $2.90. You have to add
thats a good response
The algebraic expression to represent the cost of m gallons of gasoline, where each gallon costs $1.45, would be:
C = 1.45m
In this expression, C represents the cost and m represents the number of gallons. To arrive at this expression, you multiply the cost per gallon ($1.45) by the number of gallons (m).
