Question 1181138
standard charge is S = 14.95 + .6M
insurance charge is I = 5.70 + .15M


C = total charge that includes standard charge plus insurance charge.


C = S + I = 14.95 + .6M + 5.70 + .15M


combine like terms to get:


C = 20.65 + .75M


for example, assume 100 miles, then:


S = 14.95 + 60 = 74.95
I = 5.70 + 15 = 20.70


S + I = 74.95 + 20.70 = 95.65


C = 20.65 + 75 = 95.65


that's your solution.
