Ellie is spending her entire income on goods X and Y. Her marginal utility from the last unit of X is 100 and the marginal utility from the last unit of Y that she consumes is 50. Ellie's utility is only maximized if

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.

so they can see what that city is producing and to also see if they can some how get that product. like gold in africa.

i think the answer is a. dependable person
