Okay, here we have this:

Considering the provided information, we are going to find the requested equation, so we obtain the following:

Then we can see that we must find the function that represents the total cost, therefore we have

Total cost=Standard charge+ Insurance charge

Replacing:

C=0.50M+15.75+0.25M+5.80

C=(0.50M+0.25M)+(15.75+5.80)

C=0.75M+21.55

Finally we obtain that the equation for the total charge is C=0.75M+21.55
