The smallest is 1/(5+1) = 1/6 of the total length, so is (276 in)/6 = 46 in.
The largest is 5*46 in = 230 in.
The two pieces are 46 in and 230 in.
Okay so first I am taking it that you have to subtract 24k from the 104k which brings it to 80,000.
I am also taking it that the 8.5% is suppose to be in decimal form which makes it .085%
Take the 80,000 and use the monthly payment formula, which is really easy to use.
Monthly payment should be 644.18
1% of 120 is 1.2, so 7 *1.2 = 8.4
Also you could set up the proportion 7/100 = x/120 and solve for x.
