define the variables

Question

1)    A moving van rental company charges a $35.00 rental fee plus $1.50 per mile driven. Write an equation that models the relationship between the total cost and the miles driven. Define your variables.

Answer 1

Let S be the total cost for renting the van, and m be the miles traveled.

There is a base rental fee of $35, plus $1.50 for every mile driven.

S = 35 + 1.5m

The variables are the miles driven, m, and total cost, S.
