If the winner’s prize increases at the same rate, what will it be in 2049? (Do not round intermediate calculations. Round your answer to 2 decimal places, e.g., 32.16.)

Explanation:

The time line is:

0		119
–$140		$1,420,000

To answer this question, we can use either the FV or the PV formula. Both will give the same answer since they are the inverse of each other. We will use the FV formula, that is:

    

FV = PV(1 + r)t

Solving for r, we get:

r = (FV / PV)1/t – 1

r = ($1,420,000 / $140)1/119 – 1

r = .0806, or 8.06%

To find the FV of the first prize in 2049, we use:

0		35
–$1,420,000		FV

  

FV = PV(1 + r)t

FV = $1,420,000(1.0806)35

FV = $21,407,738.35
