Answer:
The function for the standard charge is given below as
[tex]S=0.50M+16.95[/tex]
The function for the insurance charge is given below as
[tex]I=0.25M+5.70[/tex]
Concept:
To figure out the total charge C that includes insurance, we will use the formula below
[tex]C=S+I[/tex]
By substituting the functions, we will have
[tex]\begin{gathered} C=S+I \\ C=0.50M+16.95+0.25M+5.70 \\ collect\text{ similar terms, we will have} \\ C=0.50M+0.25M+16.95+5.70 \\ C=0.75M+22.65 \end{gathered}[/tex]
Hence,
The equation connecting C to M is C = 0.75M + 22.65
