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.
...subtract 40 on both sides
.... divide both sides by 25
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.
