B) Plug the values into the equation.C = 20 + 40(3) + .1(970) = 237-A) 20 + 40d + 0.B) 20 + 40(3) + 0.......
Can you tell me how to do this in detail?
A car rental company charges a one-time application fee of 20 dollars, 40 dollars per day, and 10 cents per mile for its cars.

(A) Write a formula for the cost, C, of renting a car as a function of the number of days, d, and the number of miles driven, m C=____

(B) If C = f(d, m), then f(3, 970) =___

-
A) C = 20+ 40d +.1m

20 is a flat rate so it is left as a constant. 40 is per day, and 'per' means to multiply a number by a variable because it is a rate. The same concept is for the miles driven. However, it is in a decimal because all of the numbers need to stay in the same form (dollars).

B) Plug the values into the equation.
C = 20 + 40(3) + .1(970) = 237

-
A) 20 + 40d + 0.1m
initial cost + time + distance

B) 20 + 40(3) + 0.1(970) = 20 + 80 + 97 = 197$
