Answer:
$9.00.
Explanation:
The computation of the value of a put option is shown below:
Data provided in the question
Current price of the stock = $50
Risk free rate = 6%
Strike price = $55
Sale price = $7.20
Based on the above information
The value of put option is
Put = V - P + X exp(-r t)
= $7.20 - $50 + $55 e RF - 0.06(1)
= $7.20 - $50 + $51.80
= $9.00
Hence, the value of put option is $9
