WHEN during the quarter is the contribution made ?? What about TAXES ?? {This is a reality section, not a homework section.} And why compound quarterly when the standard in the U S is monthly? Create an excel spreadsheet if you must ( i e do not know how to use TMV functions). P S 4.3% per year, or APR. {they are different.}

At 1,300 per quarter for 14 yrs, N 56, R 1.075%, PV 0, PMT 1,300 = FV of 99,152

At 1,900 per quarter for 17 yrs, N 68, R 1.125%, PV 0, PMT 1,900 = FV of 192,506

But you didn't say what happens to the 99,152 in yr 14. Does it continue to earn 4.3% over the next 17 yrs, or does it earn 4.5%. And is it compounded quarterly? Or is it disbursed in yr 14?
