Thread: Economics Help: Indifference Curves

Hi guys,
I know this is an economics question but im hoping someone can help me with this question:


David is confused. He has a limited income that he must allocate between his two favourite goods, A and B. David’s utility function for these goods is given by:
U(A,B)=4A+4B.
The price of good A is currently $6 and the price of B is currently $4.

a) Draw a graph indicating the indifference curves corresponding to level of utility equal to 24utils and 36utils.


Can someone help me with drawing this graph?
Your help will be appreciated

an indifference curve shows the combinations of A and B that give the same Utility.

For example, for a utility of 24 utils:

24 = 4A + 4B
6 = A + B
A = 6 - B

that is the equation of a straight line, which you can draw.
