Suppose consumer income increases. if grass seed is a normal good, the equilibrium price of grass seed will a. decrease, and producer surplus in the industry will decrease. b. increase, and producer surplus in the industry will increase. c. decrease, and producer surplus in the industry will increase. d. increase, and producer surplus in the industry will decrease.

b. increase, and producer surplus in the industry will increase

Explanation:

A normal good is a good whose demand increases as income increases.

If grass seed is a normal good, when income rises, demand increases and the demand curve shifts to the right. This would lead to an increase of demand over supply which would lead to a rise in price.

The rise in price increases producers surplus.

Producers surplus is the least price a producer is willing to sell a product and the actual price the product is sold. If price rises, producer surplus increases.
