Butterfly Vertical Spread:

Buy $1$ call with $K=40$

Write $2$ calls with $K=50$

Buy $1$ call with $K=60$

Suppose the future value of the costs of these three call options are $C(40)=$$$2\mathrm{.}78,C(50)=$$$\mathrm{.}267$ and $C(60)=$$$\mathrm{.}011.$ Please draw the payoff table and the profit diagram?
