Answer:
(9)(9) = .013. (53). 2. A company that manufactures video cameras produces a basic model and a deluxe model. In the past, 40% of cameras sold have been the basic model. Of those basic models sold, 30% of purchasers buy the extended warranty as well. Of the deluxe models sold, 50% purchase the extended warranty,.
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.
To find 1/4 of 12 you would divide 12 by 4 to get 3. To find 1/3 of 12 you would divide it by 3 to get 4. 4 is greater than 3 so therefore 1/3 is greater.
You add each number to get the next number and you find that the answer is 146:D
