Question

Translate the following phrase into an algebraic expression using the variable m. Do not simplify

the cost of renting a car for one day and driving m miles if the rate is $48 per day plus 50 cents per mile

Answer 1

48 + 0.50m

Explanation:

m, the variable, equals to the number of miles driven. Since there is a base fare of $48, that will be the constant. It is $0.50 per mile, so it's 0.50m. Substituting for m, the miles driven, will give you the final cost.

Answer 2

y = 0.5X + 48
