Danny owns two investments, A and B, that have a combined total value of $25,000

First we calculate Present Value of Investment A:

Present Value = Future Value / (1 + Expected Return)^ Number of Periods

= $25,000 / (1 + 12%)^4

Present value = $15,887.95

The amount in Investment A today = $15,887.95

Investment B value today = Today Investment - Amount in Investment A today

= $25,000 - $15,887.95

Investment B value today = $9,112.05

Investment B has a expected return = 8%

Now We Calculate the Value X, the cash flow expected from investment B in 7 years from today:

Future Value = Present Value * (1 + Expected Return)^Number of Periods

= $9,112.05 * (1 + 8%)^7

Future value = $15,616.45

So, Value X, the cash flow expected from investment B in 7 years from today is $15,616.45
