Can someone please help me with this?

In two or more complete sentences, explain how you can use the two functions, C(m) and T(m) to determine how many miles, m, a car needs to be driven, during a one-day car rental, in order for the total cost to be same at both car rental companies. In your final answer, include a solution for the number of miles, m. C(m) charges a flat rate of $41 and an extra fee of $0.10 per mile driven. T(m) charges a fee of $0.25 per mile driven.

164.1

Step-by-step explanation:

Company A:

c= 0.25m+30       m is the number of miles, which costs .25 cents.  Hence, .25m

Company B:

c= 0.10m+40      it charges 10 cents per mile, which is 0.10 m

Now, make the two equations equal to each other.  The answer that we get will be the exact number when you pay the same cost for either company A or B.  In other words, at that number of miles you don't care which company you choose.  However, if you go beyond that number of miles or below that number of miles, it will make a difference.

0.25m+30=0.10m+40     Subtract 30 from both sides

         -30              -30

0.25m=     0.10m+10      Subtract 0.10m from both sides

 -0.10m    -0.10m

0.15m= 10                      Divide both sides by 0.15

    m= 66 2/3

i think the answer would be c
