Answer:
You have to deposit 13584.54 dollars in 8 years in order to have 57411 dollars on your account in 19 years.
Step-by-step explanation:
In order to asses the present value of furture cash flow, we need to look at the formula for present value:
PV is Present Value, FV is future value, r is the interest rate, n is the number of years.
When we apply the numbers of the question, FV is 57411, r is 0.14 and n is 11 because we will put our deposit in 8 years and 19 - 8 is 11.
When we insert the numbers into the equation we get 13584.54
I hope this makes the answer clearer! :D
