Suppose Mary is in consumer equilibrium. The marginal utility of good A is 30, and the price of good A is $2.

a. if the price of good B is $4, the price of good C is $3, the price of good D is $1, and the price of all other goods and services is $5, what is the marginal utility of each goods mary is purchasing?

b. If mary has chosen to keep $10 in savings, what is the ratio of MU to P for savings?

Question

Suppose Mary is in consumer equilibrium. The marginal utility of good  A is 30, and the price of good A is $2.

a. if the price of good B is $4, the price of good C is $3, the price of good D is $1, and the price of all other goods and services is $5, what is the marginal utility of each goods mary is purchasing?

b. If mary has chosen to keep $10 in savings, what is the ratio of MU to P for savings?

anonymous · Answer

If you want to find the marginal utility of a product the formula for it is

Marginal Product good A$$Marginal utility  of good A\div Price of Good A = Marginal Utility of good B \div price of good B$$

now since marginal utility of good A is given then by using this formula 
the the marginal utility of good B is 60 , MU of good C is 45 and MU of good D is 15
