You take out an installment loan of $2700.00 for 30 months at 8 %. the title of a monthly payment table is “monthly payment on a simple interest installment loan of $100” if you use 30 months and 8% interest, you get the figure $3.69 in this table. calculate the monthly payment.

From what you wrote, according to your table: 

For every $100 you borrow at 8%, you pay $3.69 each month for 30 months. 

So, you pay back a total of 3.69 x 30 = $110.70 

But, if you borrow 2700, using your table you find that: 

2700 / 100 = 27 

27 * 3.69 = 99.63 

So you pay back 99.63 x 30 = $ 2988.90
