Is this correct

Using the previous graph, you can determine that Yakov is willing to supply his 600th pound for $1.00 . Since he receives $1.25 per pound, the producer surplus earned from supplying the 600th pound is $0.25 . Suppose the price of pork roast were to rise to $1.50 per pound. At this higher price, Yakov would receive a producer surplus of $0.50 from the 600th pound he sells. The following graph plots the weekly market supply curve (orange line) for pork roast in a hypothetical small economy. Use the purple point (diamond symbol) to shade the area representing producer surplus (PS) when the price (P) of pork roast is $1.25 per pound. Then, use the green point (triangle symbol) to shade the area representing additional producer surplus when the price rises to $1.50 per pound. ?
