PLEASE HELP. THANK YOU

Eileen takes out a 3/1 ARM with 3/4/5 caps. The initial teaser rate on the mortgage is 2.5% and the mortgage is indexed to 1 year CMT with a margin of 2%. Suppose that at the first reset the 1 year CMT is at 4%. What will be Eileen's interest in year 4? (Write the answer as a percent so for example 2.5% should be written as 2.5, not as 0.025) Joan takes out a 5/1 ARM with 2/4/6 caps. The initial teaser rate on the mortgage is 2% and the mortgage is indexed to 1 year CMT with a margin of 2%. What is the maximum interest that Joan might pay on this mortgage? (Write the answer as a percent so for example 2.5% should be written as 2.5, not as 0.025 ) Tim buys an apartment that costs $750,000 with an 85\% LTV mortgage. Tim got a 30 year, 3/1 ARM with an initial teaser rate of 3.75% and monthly payments. The reset margin on the loan is 300 basis points above 1 year CMT. The index was 1% at the time of origination. Tim also had to pay 3 points for this loan. Suppose the index rate will remain 1% for the life of the loan and Tim prepays the mortgage in 5 years. Compute the true APR for this loan.
