A vehicle rental company charges $35 to rent a moving van plus $.40 for each mile traveled. Which expression represents the total cost of renting a van and driving d miles? * A. 35 + d
B. 35 + 0.40d
C. 35 – 0.40d
D. 35d + 0.40

B

Step-by-step explanation:

B is the answer

D

Step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
