Use the given formula to solve the following problem: when the amount financed is $12,000, the monthly payment is $422.36, and the annual interest rate is 6.65%, how long do you have to pay? n = log of the quantity p divided by the quantity p minus eh r, divided by the log of the quantity 1 plus r

12000=422.36[(1-(0.0665/12)^(-X))/(0.0665/12)]
Solve for x
X=31 months

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
