A) Given:
Income: $100,
Price of Food (X) = $4,
Price of Clothing (Y) =$10
Thus, the budget constaint is:
B) Now, the new price of clothing upto 5 units is $5. Thus, the set of equations of budget constraint is
I have constructed the below diagram for greater clarity
Let me explain this:
The dotted black line indicates the budget constraint if the subsidized price of clothing continued even after the first 5 units. Thus, we need only the green part of this line, lying below the blue line.
Now, The red line indicates the inital budget line.
We can clearly see that after 5 units, there arises a kink for the budget line to be continuous. Hence, the final budget line is highlighted in green.
