If your utility schedule is like the one above, and the price of a piece of cake is $1 and the price of a salad is $3, how many pieces of cake should you eat if you have a budget of $25?

Answer 1

Answer:

Utility is maximized when MUc/Pc=MUs/Ps

where MUc=marginal utility of cake

MUs=marginal utility of salad.

Pc= price of cake

Ps= price of salad.

utility Maximization= MUc/Pc =MUs/Ps

here at 7 cake and 6 salad utility is maximized.

7 cake * $1= $7

6 salad* $3=$18

total Budget is $25.
