Assume you deposit $300 now into an account that had nothing in it previously, make an additional deposit of $400 in 1 year, and a final deposit of $200 in 4 years. How much is in your account in 6 years, if the account earns interest at 7% per year, compounded annually?
- $418.29
- $1,431.88
- $1,120.04
- $925.51
- $1,240.22
Answer(s): E
Explanation:
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.
