The cost of the carpool can be modeled by the following equation where C is cost of carpooling per week and m is the total miles driven to school each week: c= 1/2 (0.082m+ 0.22m + 25) (a) Find the total weekly carpooling cost, C, if the commute to school is 8 miles each way and Paula goes to school four times a week. C = (b) Find the number of miles, m, if the carpooling cost is $30.50. m =

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
