Given Budget Line Values:

Px = 30, Py = 50, Qx = 70, Qy = 30

Calculate Income

Budget Line Equation:

I = Px x Qx + 50 x Py x Qy
where:
I = Income
30 = Price of item x
70 = Quantity of Item x
50 = Price of item y
30 = Quantity of Item y

Plug in values

I = 30 x 70 + 50 x 30

I = 2100 + 1500

I = 3600




With a Total Income of 3600
you can buy 70 items of x at a price of 30
and 30 items of y at a price of 50

What is the Answer?
I = 3600
