Answer:
60 miles.
Step-by-step explanation:
Given:
We rent a car for the day and are offered two payment options.
With option A we pay $25 flat rate plus $0.15 per mile.
With option B we pay a $10 flat rate plus $0.40 per mile.
Question asked:
For what amount of miles would the cost of option A be equal to option B ?
Solution:
<u>Let amount of miles for which the cost of option A be equal to option B = </u>
<u />
For option A, we pay = ![25+0.15\times x](https://tex.z-dn.net/?f=25%2B0.15%5Ctimes%20x)
For option B, we pay = ![10+0.40\times x](https://tex.z-dn.net/?f=10%2B0.40%5Ctimes%20x)
Now, to find amount of miles for which the cost of option A be equal to option B, we will equalize the equation to find the value of
![25+0.15x=10+0.40x\\](https://tex.z-dn.net/?f=25%2B0.15x%3D10%2B0.40x%5C%5C)
By subtracting both sides by 10
![25-10+0.15x=10-10+0.40x\\15+0.15x=0.40x](https://tex.z-dn.net/?f=25-10%2B0.15x%3D10-10%2B0.40x%5C%5C15%2B0.15x%3D0.40x)
By subtracting both sides by ![0.15x](https://tex.z-dn.net/?f=0.15x)
![15+0.15x-0.15x=0.40x-0.15x\\15=0.25x](https://tex.z-dn.net/?f=15%2B0.15x-0.15x%3D0.40x-0.15x%5C%5C15%3D0.25x)
By dividing both sides by ![0.25](https://tex.z-dn.net/?f=0.25)
![x=60\ miles](https://tex.z-dn.net/?f=x%3D60%5C%20miles)
Therefore, for 60 miles, the cost of option A will be equal to option B.
