anonymous · Answer

we cannot direcxtly multiply percentage to a whole number, therefor let's convert percentage to decimal.  5.5% will be 5.5/100

my bad for multiplying 9 directly to the formula.
here is the right way.

for the t( number of years) , 9 months is 3/4 of a year.

therefor the interest will be

interest = 2000 ( 5.5/100) (3/4)  = 82.5
