Consider the trade-off between muffins and coffee. Suppose that at the current level of consumption, the consumer is willing to trade 2 muffins for a cup of coffee. The price of muffins is $2 each and the price for each coffee is $4.00. The consumer has $20 to spend (each week) on muffins and coffee (and always spend all of it). a) What is the consumer's MRS? b) Is the consumer currently in equilibrium?
