Question 1129150: 1.Driving will cost 22 cents per mile for gas and 8.2 cents per mile for maintenance of the car. Additionally, there is a $25 parking fee per week at the college. If Paula carpools, she would pay half of these costs. C is the cost of carpooling per week and m is the total miles driven to school each week:
C=1/2(0.082m+0.22m+25)
Find the total weekly carpooling cost if the commute to school is seven miles each way and Paula goes to school three times a week.

C=%281%2F2%29%280.082m%2B0.22m%2B25%29

m+is the total miles driven to school each week

if the commute to school is 7 miles each way:=>14 miles to school and back
and, if Paula goes to school 3 times a week, the total miles driven to school each week will be m=3%2A14=42
C=%281%2F2%29%280.082m%2B0.22m%2B25%29...plug in m
C=%281%2F2%29%280.082%2A42%2B0.22%2A42%2B25%29
C=%281%2F2%29%283.444%2B9.24%2B25%29
C=%281%2F2%29%2837.684%29
C=18.84
