Two partners agree to invest equal amounts in their business. One will contribute​ $10,000 immediately. The other plans to contribute an equivalent amount in 8 years. How much should she contribute at that time to match her​ partner's investment​ now, assuming an interest rate of 4​% compounded quarterly​?

1 answer

To solve this problem, we need to use the formula for future value of a lump sum:

FV = PV x (1 + r/n)^(n*t)

Where:
FV = future value
PV = present value
r = interest rate
n = number of compounding periods per year
t = number of years

First, we need to find out how much the $10,000 investment will be worth in 8 years at a 4% quarterly interest rate. We can plug in the values:

FV = 10,000 x (1 + 0.04/4)^(4*8) = 10,000 x 1.3659 = $13,659

So the partner who plans to invest in 8 years needs to contribute $13,659 to match her partner's investment now.
