Find the answer to this question by solving 3 compound interest problems. On the BAII Plus, press 3 N, 10 divide 12 = I/Y, 0 PMT, 800 FV, CPT PV which yields
$849.21. Then press STO 1. Then press 7 N, 900 FV, CPT PV, which yields $780.33. Then press + RCL 1 = STO 1. Then press 11 N, 1200 FV, CPT PV, which yields $1,095.31. Press + RCL 1 = to see the answer. On the HP12C, press 3 n, 10 ENTER 12 divide i, 0 PMT, 800 FV, PV. Then press STO 1. Then press 7 n,
900 FV, PV. Then press RCL 1 + STO 1. Then press 11 n, 1200 FV, PV. Press RCL 1 + to see the answer. Make sure the BAII Plus has the P/Y value set to 1.
