Mr. R. Plane, a retired college administrator, consumes only grapes and the composite good C (Pc = $1). His income consists of $10,000/yr from social security, plus the proceeds from whatever he sells of the 2000 bushels of grapes he harvests annually from his vineyard. Last year, grapes sold for $2/bushel, and Mr. Plane consumed all 2000 bushels of his grapes (did not sell any) in addition to 10,000 units of C. This year, the price of grapes is $3/bushel, while Pc remains $1. If his indifference curves have the conventional shape, will this year's consumption of grapes be greater than, smaller than, or the same as last year's? Will this year's consumption of C be greater than, smaller than, or the same as last year's? Explain briefly and graph.
