## mskyeg 2 years ago A rental car agency charges a flat fee of \$110.00 plus \$46.00 per day to rent a certain car. Another agency charges a fee of \$70.00 plus \$54.00 per day to rent the same car. Using a graphing calculator, find the number of days for which the costs are the same. Round your answer to the nearest whole day.

Well, you set up two separate equations for cost. Agency A would be y=110+26x and Agency B would be y=70+54x. Then let equation A equal equation B and solve.

I'm confused I just ntered it into a graphing calculator and it didn't show that any days existed where the costs are the same

3. dylanhouse

Sorry, equation A should be y=110+46x.

Same thing they didn't intersect at any point

6. dylanhouse

They should intersect at x=5.

7. mskyeg

thats one intersection but what about the others and how many of them are there how do i know

@MeganDarling just asked this identical question on line homework?

9. mskyeg

11. mskyeg

i have no idea, it is just that i answered this question 5 minutes ago exact same

14. dylanhouse

That's the only solution when you solve the equation. So it's the only days they would be equal.

15. mskyeg

oh cool that was easier than I expected thanx:)
