So hmm notice the picture below
you have the center, and a point on the circle... all you need is the radius

then use that radius in the circle's equation
I'm Not Completely sure but the closest Answer seems to be C.
The most right answer would be the one you think because I think that’s right 4x4
1. The problem gives the residual value in percentage, and you need it in dollars. So, if the MSRP for the car Jennifer is leasing is $ 17,500, you have:
57%/100=0.57
residual value=$17,500*0.57= $9,975
2. Then, you need to substract the residual value and the lease term, to calculate the value of the car, as below:
car value=$17,500-$9,975=$7,525
3. You need to calculate the money factor, which is the interest rate divided by 2400. Then, you have:
Interest rate=9%/100=0.09
Money factor=0.09x2400
Money factor=0.00375
4. The interest is:
I=($17,500+$9,975)(0.00375)
I=$103.03
5. Therefore, the monthly payment is:
Monthly payment=(car value/36 months)+Interest
Monthly payment=($7,525/36)+$103.03
Monthly payment=$209.02+$103.03
Monthly payment=$312.06
What will Jennifer’s monthly lease payment be?
The answer is: d. $312.06
42. they’re across from each other
