Consider a 3-month call option on a dividend paying stock when:

- the current stock price is $9.00

- the exercise price is $6.00

- the volatility is 20% p.a.

- the risk-free rate of interest (continuous compounding) is 10% p.a.

- the time to expiry is 3 months

- the stock is expected to pay a dividend of $1.25 in 1.25 (one and one-quarter) months time.

Use the Binomial Option Pricing model with the life of the option divided into three 1-month periods.
