Question
Nigel’s Pub has a total budget of £128 per week to spend on cod and lamb. The price of cod is £16 per kilogram, and the price of lamb is £10 per kilogram.
Construct a diagram of Nigel’s budget constraint.
Answer

On the other hand, if he chooses to spend the entire budget on lamb, he could buy 12.8kg. Of course, he could spread his £128 between the two goods in any proportions he chooses, so the budget constraint is drawn as follows:
