Question

Amanda and her husband are each starting a saving plan. Amanda will initially set aside

Answer 1

The problem ask us to find C, which is the total cost of the rental and the insurance.

Then, to find C in terms of M, we need to add the functions S and I:

Standard charge:

S(M) = 16.15 + 0.6M

Insurance Fee:

I(M) = 4.9 + 0.15M

Then the function C(M) that represents the total charge for a rental with insurance, after driving M miles is:

`C(M)=S(M)+I(M)`

Then write:

`\begin{gathered} C(M)=16.15+0.6M+4.9+0.15M \\ \end{gathered}`
`C(M)=21.85+0.75M`

The answer is:

`C(M)=21.85+0.75M`
