Arlene is comparing the prices of two truck rental companies. company a charges $7 per hour and an additional $30 as service charges. company b charges $8 per hour and an additional $40 as service charges.

part a: write an equation to represent each company's total charges for renting a truck for a certain number of hours. 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 truck for 8 hours? 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 truck for 2 hours? (3 points)

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
