We claimed that our model for Barney-Jones is generalizable. Try generalizing it to the case where there are two more potential investments, F and G. Investment F requires a cash outlay in year 2 and returns $0.50 in each of the next four years. Investment G requires a cash outlay in year 3 and returns $0.75 in each of years 5, 6, and 7. Modify the model as necessary, making the objective the final cash after year 7.
