# Marginal Rate of Substitution

I am a graduate student surviving on a limited income and my money income is $300 per month, the price of good X is $4, and the price of good Y is also $4. Given these prices and income, I buy 50 units of X and 25 units of Y. The combination of X and Y bundle J. At bundle J my marginal rate of substitution (MRS) is 2. At bundle J, if I increase consumption of Y by 1 unit, how many units of X can I give up and still reach the same level of utility?
