I’m stuck please help! (Urgent) Compound interest

What are you trying to figure out? The monthly payment? If so, use this formula:

PMT=PV. R.{[1 + R]^N / [1 + R]^N - 1}

PMT=153,000 x 0.45/12 [[1 + 0.45/12]^(30*12) / [1 + 0.045/12]^(30*12) - 1

PMT=153,000 x 0.00375[[1 + 0.00375]^360  / (1.00375)^360 - 1]

PMT=573.75 x                                      1.3511608262......

PMT=$775.23 - The monthly payment.       

P   =    1530000 (0.045/12)             =        573.75       ≈     $775.23

           ___________________               ________

             1  - ( 1 + 0.045/12)^(-360)             0 .74...
