Question

A car rental company's standard charge includes an initial fee plus an additional fee for each mile driven. The standard charge S (in dollars) is given by the function =S+17.75+0.60M, where M
is the number of miles driven.The company also offers an option to insure the car against damage. The insurance charge I (in dollars) is given by the function =I=3.70+0.25m.
Let C be the total charge (in dollars) for a rental that includes insurance. Write an equation relating
C to M
. Simplify your answer as much as possible.

Answer 1

@Directrix plz help

Answer 2

Is this supposed to be S = rather than = S

>> =S+17.75+0.60M,

This "=S+17.75+0.60M," is not an equation.

Answer 3

Same question here:

=I=3.70+0.25m.

Answer 4

yes stupid computer

Answer 5

S = 17.75 +.6*M where M
I = 3.70 + .25*M

C = S + I

C = 17.75 + .6*M + 3.70 + .25*M

@Missiey

Add 17.75 to 3.70

Then, add .6M to .25 M

Post what you get, okay?

Answer 6

ok

Answer 7

c=21.45+0.85m

Answer 8

Usually, the variable is written first (doesn't have to be).

C = .85*M + 21.45 That would be the cost of the car rental and insurance based on miles the car is driven.
