This is a question from a text book. plz help and solve it.
The Huang family purshased a motor home by borrowing $30,000 at 9%/a compounded monthly. The Huang will make payments at the end of each month. They have two choices for the term: 5 years and 8 years
a) Determine the monthly payments for each term.
b) How much money would they save by choosing the shorter term.
I tried to do find the total amount after 5 years which is $46,970.43 and 8 year is $61,467.64. As I subtracted the 5 year total from 30,000 and divide by 5x12 months, I got $282.84 for a) but the book says its $622.75 so apparantly im wrong. The book also says for 8 year term it is 439.51 and b) is $4827.96.
