In the below figure, a consumer is initially in equilibrium at point C. the consumer’s income is $300, and the budget line through point C is given by $300 = $50X + $100Y. When the consumer is given a $50 gift certificate that is good only at store X, she moves to a new equilibrium at point D.Determine the prices of goods X and Y
