Acompany rents cars at $45 a day and 12 cents a mile. its competitor's cars are $60 a day and 5 cents a mile. (a) for each company, give a formula for the cost of renting a car for a day as a function of the distance traveled. assume distance m is measured in miles. assume cost c is measured in dollars. first company: c(m) =

The formula for the cost of renting a car for a day for two companies will be as follows:
The cost of renting a car follows a linear model given by:
f(x)=mx+c
where:
where f(x)= total cost
x=independent variable which is number of miles
m=slope=cost of renting per mile
c=constant daily payments

thus;
formula for:
company a will be:

C(m)=0.12m+45
C(m) is total cost, m is number of miles

company b:
c(m)=0.05m+60
where:
c(m) is the total cost, m is the number of miles in a day.
