The principal is $861 .

Interest rate 20.8% .

Interest is compounded monthly .

Formula for compound interest is image 

P = principal amount (the initial amount you borrow or deposit) = $861

r  = annual rate of interest (as a decimal) = 0.208

t  = number of years the amount is deposited = one month = 1/12

A = amount of money accumulated after n years, including interest.

n  =  number of times the interest is compounded per year = 12 times .

image

He made a payment of $73 this month , so $73 has to subtract from net amount .

Balance amount = 875.924 - 73 = 802.924

So the Balance amount is 802.924 .

Option (c) is correct .
