Answer:
Clarissa needs to fund the growing perpetuity by $166666.67
Explanation:
A perpetuity is an investment that will give a future series of infinite payments so if the perpetuity gives you a periodic growth rate then you find the difference between the interest rate and the growth rate then use the perpetuity formula which is:
Pv = C/(i-g)
where Pv is the present value of the perpetuity which will be the initial investment.
C is the periodic payments that will be received in future in this case $5000
i is the interest rate given for the perpetuity which is 8%
g is the growth rate per fixed period which is 5%
thereafter we substitute on the above mentioned formula:
Pv= $5000/(8%-5%) then compute
Pv = $166666.67 which will be the initial investment for Clarissa to be paid $5000 per year until she dies.
