Answer:
The price of good X is twice the price of good Y
Explanation:
Utility can be defined as the amount of satisfaction that one can derive from consuming a product.
Marginal utility is the additional utility derived from consuming an extra unit of a product.
Total Utility is the total satisfaction one derives from consuming all units of a product.
Because consumers are rational and they want to spend the least amount to get maximum utility, they are at equilibrium at the point where Marginal Utility of product X divided Price of X is equal to the Marginal Utility of product Y divided by Price of Y.
So for utility to be maximized it means that the price of good X has to be twice the price of good Y.
