For each of the following, draw the indifference curves and budget constraint, and find the utility maximizing demands. Remember, don’t plug in the given prices and income until the end.
u(x1,x2)=(x1)^2(x2), (p1,p2,m)=(1,2,10)
The MRS would be as
or
or
or
or
or
, ie
. The budget constraint would be
, and the slope would be as
or
or
.
The optimal combination of goods would be where MRS is equal to
the slope of budget constraint, ie where
or
or
. Putting this in the budget constraint, we have
or
or
and since
, we have
or
or
. These are the required demand for good 1 and 2.
For the given values, we have the demands as
or
and
or
. The utility level would be
or
or
.
We have the graph as below.
