Jake wears Levi’s and T-shirts with surfer logos. He has lots of these, even some that he hasn’t worn and can take back to the store for a refund if he wants. His marginal rate of substitution (MRS) of Levi’s for T-shirts is 3, meaning that if given the opportunity he would be willing to trade 3 T-shirts for 1 pair of Levi’s, or vice versa. The price of Levi’s is $20 and the price of T-shirts is $10. Suggest a way that Jake can make himself even happier than he is now.
