Hey everyone, im having a bit of trouble remembering how to do these questions from corporate finance

A 29 year old loan requires weekly payments of 125.43 including interest at 24.50% compounded weekly.

a) What was the original amount of the loan?

b) What is the loan's balance 23.00 years later (just after the schedualed payment)?

I have a texes instruments BAII Plus calculator so im able to use that to do the calculations

Thanks in advance

So far I have:

PV = Compute

I/Y = 24.50

N = 52*29 = 1508? (compounded weekly)

PMT = 125.43

FV = no clue how to calculate this
