mabel is comparing the prices of two car rental companies. company a charges $35 per day and an additional $15 as service charges. company b charges $42 per day and an additional $10 as service charges.

part a: write an equation to represent each company's total charges for renting a car for a certain number of days. for both equations (one for company a and one for company b), define the variable used. (4 points)

part b: which company would charge less for renting a car for 6 days? justify your answer. (3 points)

part c: how much money is saved by using the services of company a instead of company b to rent a car for 10 days? (3 points)

P = total Price

X = number of days

 Part A

Company A : P=35x+15

Company B: P=42X+10

Part B

X=6

Company A : 35(6) +15 = 225

Company B: 42(6)+10 = 262

 so Company A is cheaper

Part C

 x = 10

Company A: 35(10)+15 = 365

Company B: 42(10) +10 = 430

430-365 =65

 so you save $65 using Company A

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
