Question

What happens to the original budget line if the price of good ? doubled? (i.e., Will there be a 
change in the slope and/or intercepts of the original budget line? If yes, what are those changes?). 
Interpret economically how the change in the price of good ? affects the consumption decision 
of the consumer

Assume that a consumer spends all of her income (B) on good X and good Y, her budget constraint
can be expressed as:
PxX + PyY = B
Where Px is the price of good X, X is the quantity of good X consumed, Py is the price of good Y, Y
is the quantity of good Y consumed, and B is the consumer's total income.
Rearranging the above equation to get the budget line expressed as Y in terms of X, we have:
B
Y ==
Py Py
Px
-X
Now, suppose the consumer has an income of $120 to spend on goods X and Y whose prices are $3
and $5, respectively.
