Add 6 to both sides and you get your final answer.
Answer:
After 0.4 miles the Unlimited Mileage Plan is a better deal.
Daily Mileages > 0.4
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.
First we can create a Formula to calculate the price of each plan, like so...
Unlimited Mileage: 50x = Total
Per mile: 40x + 25y = Total
- X being the days rented
- Y being amount of miles
Since we want to calculate at what daily mileage the unlimited plan becomes better than the regular, we can substitute x for 1 and equal both plans together. Then solve for the minimum amount of miles in which the prices meet.
![50(1) = 40(1) +25y](https://tex.z-dn.net/?f=50%281%29%20%3D%2040%281%29%20%2B25y)
...subtract 40 on both sides
.... divide both sides by 25
![0.4= y](https://tex.z-dn.net/?f=0.4%3D%20y)
Now we can see that at 0.4 miles both prices are the same. This means that after 0.4 miles the Unlimited Mileage Plan is a better deal.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
Slope formula is
![\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=%20%5Cfrac%7By2-y1%7D%7Bx2-x1%7D%20)
![\frac{5-1}{-2-3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5-1%7D%7B-2-3%7D%20)
![\frac{4}{-5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B-5%7D%20)
So -4/5 is the right answer.
Hope this helps :)
