Solve this question by working several compound interest problems, moving each dollar amount over to year 5. On the BAII Plus, press 6 N, 7 I/Y, 300 PV, 0 PMT,

CPT FV, which yields $450.22. Then press STO 1, 5 N, 400 PV, CPT FV, which yields $561.02. Then press + RCL 1 = STO 1. Then press 2 N, 200 PV, CPT FV, which yields $228.98. Then press + RCL 1 = to see the answer. On the HP12C, press 6 n, 7 i, 300 PV, 0 PMT, FV. Then press STO 1, 5 n, 400 PV, FV. Then press RCL 1 + STO 1. Then press 2 n, 200 PV, FV. Then press RCL 1 + to see the answer. Note that the answer will be displayed as a negative number. Also note that the value of "N" for each dollar amount is based on the distance from year 6.
