Answer: Melinda’s loan will be equal to the value of the car after 10 months.
Step-by-step explanation:
Hi, to answer this question we have to equal both equations:
Melinda’s loan will be equal to the value of the car
y = y
10,000 – 250x = 8,000 – 50x
Solving for x:
10,000-8,000 = -50x+250x
2,000 = 200x
2,000/200 =x
10 = x
Melinda’s loan will be equal to the value of the car after 10 months.

The formula for the area of a rectangle is:
![A=wl](https://tex.z-dn.net/?f=A%3Dwl)
w = width
l = length
First, we have to convert 2
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
into an improper fraction, then into a number. The improper fraction would be
![\frac{5}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B2%7D%20)
. Let's convert that into a decimal.
![5/2=2.5](https://tex.z-dn.net/?f=5%2F2%3D2.5)
Let's multiply
![2.5*10=25](https://tex.z-dn.net/?f=2.5%2A10%3D25)
The area of the rectangle would be 25 feet!
