Sarah and Sahar went trick or treating at the same houses and therefore have the same allocation of two types of candy, Snickers and Milky Way. (These are candy bars but in effect the individual have two goods.). Sarah's MRS is 3, she is willing to give up 3 snickers for 1 milky way and remain equally satisfied, while the MRS for Sahar is 1. Given their allocations and marginal rates of substitution can Sarah and Sahar trade and make each other better off? Explain
