6:15 is in ratio form..... If you mean fraction form, a ratio is equivalent to a fraction, so the answer is 6/15
(y^2-y-12)/(y^2-2y-15) factor both the numerator and denominator...
(y^2-4y+3y-12)/(y^2-5y+3y-15)
(y(y-4)+3(y-4))/(y(y-5)+3(y-5))
((y-4)(y+3))/((y-5)(y+3)) so the (y+3) terms cancel leaving
(y-4)/(y-5)

We start by figuring out the present value of the remaining balance for the home, which is 190000 - 19000 = 171000. We must also figure out the monthly interest rate, since the rate given does not say it is a nominal rate, nor does it say it is compounded monthly, so we assume that is is NOT a nominal rate. Let's call them i7 and i9. So i7 = (1.07^(1/12) - 1) = .00565415 and i9 = (1.09^(1/12) - 1) = .00720732.
Now we just have to figure out the monthly payment under both interest rates. At 7%, we have 171000 = x * a angle 300
which becomes 171000 = x * (1 - 1.00565415^-300)/.00565415
So, the monthly payment, x7 is 1185.24.
At 9%, we have 171000 = x * a angle 300 (at the i9 rate)
which becomes 171000 = x * (1 - 1.00720732^-300)/.00720732
So, the monthly payment, x9 is 1394.13.
The difference between monthly payments would be 1394.13 - 1185.24 = 208.89, which is the final answer.
