Answer:
(a) $4,000,000 (b) $45,342,380.97 (c) 2,977,256.60
Explanation:
Solution:
(A) The annual payment is determined by dividing the advertised prize by the number of payments which is stated as follows:
Amount of annuitized prize = $80,000,000/20 = $4,000,000
(B) Since, cash prize is present value of annuity payments discounted at an interest rate of 7%,
Amount of cash prize can be calculated using the formula:
P * [(1-((1+r)^(-n))/r] * (1+r)
= $4000000 * [(1-((1+7%)^(-20))/7%] * (1+7%) = $45,342,380.97
Amount of cash prize = $45,342,380.97
(C) Now, let make an assumption that the amount received at time 0 is x
The Amount received at time 1 = (1+3%) * x = 1.03 x
Amount received at time 2 = (1+3%)2 * x = 1.032 x
So, on till amount received at time 19 = (1+3%)19 * x = 1.0319 x
Then
The Sum of this series can be find using the formula is shown below:
A(1-rn)/(1-r)
A is the first term i.e. A = x
r is the common ration i.e. r = 1.03
n is number of terms i.e. n = 20
Hence, sum of the payments = x * (1-1.0320)/(1-1.03) = 26.8703745*x
Since sum of series of payments is $80,000,000
Therefore, 26.8703745*x = 80,000,000
x = 80,000,000/26.8703745
x = 2,977,256.60
Therefore as a graduated annuity payment, first amount received is $2,977,256.60
