If a producer is willing to accept 15 for a chocolate cake.but is able to sell it at a price of 40 then producer surplus would be: 5 25 15 30

To calculate the producer surplus, we need to find the difference between the price at which the producer is able to sell the chocolate cake and the minimum price at which the producer is willing to accept.<br /><br />In this case, the producer is willing to accept $15 for the chocolate cake, but is able to sell it at a price of $40.<br /><br />Therefore, the producer surplus would be:<br /><br />Producer surplus = Selling price - Minimum acceptable price<br />Producer surplus = $40 - $15<br />Producer surplus = $25<br /><br />So, the correct answer is $\$ 25$.
