SOLUTION
The standard charge is
[tex]S=0.60M+18.95[/tex]
And the insurance charge is
[tex]I=0.15M+4.80[/tex]
The total cost will be given as:
[tex]C=S+I[/tex]
Substitute for S and I into the equation
[tex]C=0.60M+18.95+0.15M+4.80[/tex]
Simplify the equation:
[tex]C=0.75M+23.75[/tex]
Therefore the required answer is:
[tex]C=0.75M+23.75[/tex]
