Suppose that call options on a stock with strike prices $30 and $40 cost $8 and $4, respectively. To create a bull spread by buying the $30 call and selling the $40 call.

a. Construct a table that shows the profit for the spread. (You can refer the table below as a hint)

b. Plot the profit with important number and formula.

Stock Price ST	Buy $30 call	Sell $40 call	Overall Profit
$40 <
$30 to $40
< $30

Need both solved ASAP, please.
