Jacob sells homemade skateboard decks for a profit of $27 per deck. He is considering switching to a new type of material that will increase his profit, as expressed by the function y = 32x, where x is the number sold and y is the amount of profit. How many more dollars will Jacob earn on each skateboard deck if he switches to the new material? Explain how you found your answer.
