When the own price elasticity of good X is 0.5, then total revenue can be increased by: decreasing the quantity supplied. decreasing the price. increasing the price. neither increasing the price, decreasing the price, nor decreasing the quantity supplied.

The demand function for good X is given by Q_X^d = 10000 - 3P_X + 9P_Y - 0.05M, where Q_X^d is the quantity demanded for good X, P_X represents the price of good X, P_Y is the price of good Y, and M is income. If P_X = $290, P_Y = $298 and M=$51,486. What is the income elasticity of demand between good X and good Y?
