To solve this question, choose a future value that is twice the size of the present value. The actual number will not matter. On the BAII Plus, press 7.25 I/Y, 1000
PV, 0 PMT, 2000 +/- FV, CPT N. On the HP12C, press 7.25 i, 1000 PV, 0 PMT, 2000 CHS FV, n. Note that the HP12C will show 10 for the answer. The answer will be the same as long as the FV is twice as large as the PV. Make sure that the BAII Plus has the P/Y value set to 1.
