If the final answer is within a penny, it's close enough for me. Either round final percent answers to the nearest tenth of a percent or down to the lower tenth of a percent for savings plans. A tenth of a percent is like 2.8%. 1. Pat has a $400,000 mortgage loan with a 30 -year term and an interest rate of 5.25%, compounded monthly. a) How much is Pat's monthly mortgage payment? b) How much interest was charged on their loan in the very first month?

Hint: Find the total payment amount. Subtract that from what they borrowed. f) Over the entire loan, what percentage of their payments went to interest
