Upon graduation from college, warren roberge was able to defer payment on his $22,000 student loan for 3 months. since the interest will no longer be paid on his behalf, it will be added to the principal until payments begin. if the interest is 6.94 % compounded monthly , what will the principal amount be when he must begin repaying his loan?

It sounds to me as I read it, as the principal P, will have the 3 months of interest added, because Warren deferred payments for 3 months, but that doesn't let him off the hook on the interest payments, so what the loaning bank did is say, "ok, start paying it in 3 months, but we'll accumulate the monthly interest to it".

so in short what is a principal of 22,000 accumulating 6.94% monthly compounding interest rate for 3 months?

bearing in mind that 3 months is not even a year, since there are 12 months in a year, 3 months is really just 3/12 year.
