Question

Question One: If Julie’s group decides that they need the limo service for 3 hours which is most economical company to use?

We can solve for both equations using 3 for x. Remember from our word problem, x is the hours rented.


Go-Limo Lime Limo
Y = 300 + 100x

Y = 300 + 100(3)

Y = 300 + 300

Y = 600
Y = 200 + 150x

Y = 200 + 150(3)

Y = 200 + 450

Y = 650


For a three hour rental the Go-Limo would be the best buy.

Question Two: If Julie’s wants to find the time where one company would be a better buy than the other she can use the substitution method.

Go-Limo Lime Limo
Y = (300 + 1

Answer 1

y=300+100x
y=200+150x

substitution means that you express y or x from 1 of the equations and plug that in to the other. Lets use this: y=300+100x
300+100x=200+150x
100=50x
x=2

Answer 2

meaning that if the work takes 2 hours than the price is = for the 2 companies

Answer 3
