= The price of lettuce is $21b (PL = $2) and the price of broccoli is $4/b (P = $4). The marginal rate of substitution at the initial point of production and consumption is -1.5 (MRS = -1.5) where the set-up of the axes is such that lettuce is on the vertical (y) axis and broccoli is on the horizontal (x) axis. Assume that the current total expenditure is $150. Explain why it makes sense to purchase and consume 0.1 fewer lbs. of broccoli if you want to move towards (but not necessarily achieving) maximization of total utility without changing the budget. You will need to make calculations and explain them to get credit for this
