Consider the usual consumer’s spending plan problem. Consumers have a minimal amount of income to invest on the things they need and want. Suppose Alphonso has ?10 in security money each week that he can allocate in between bus ticket for obtaining to work and also the burgers the he eats because that lunch. Burgers cost ?2 each, and bus tickets are 50 cents each. We deserve to see Alphonso’s budget plan problem in (Figure).

You are watching: The slope of a budget constraint line is influenced by

Each point on the budget constraint represents a combination of burgers and also bus tickets whose complete cost adds as much as Alphonso’s budget of ?10. The family member price the burgers and also bus ticket determines the steep of the budget plan constraint. All along the budget plan set, offering up one burger means gaining 4 bus tickets.


Explain why people make selections that are straight on the spending plan constraint, quite than within the budget plan constraint or external it.

Suppose Alphonso’s town raises the price of bus ticket from ?0.50 come ?1 and the price that burgers rises native ?2 to ?4. Why is the opportunity price of bus tickets unchanged? suppose Alphonso’s weekly safety money increases from ?10 come ?20. Just how is his spending plan constraint impacted from all 3 changes? Explain.


Use this info to prize the complying with 4 questions: Marie has actually a weekly budget of ?24, i beg your pardon she likes to spend on magazines and pies.

If the price the a magazine is ?4 each, what is the maximum number of magazines she might buy in a week?

Draw Marie’s budget constraint v pies on the horizontal axis and also magazines ~ above the vertical axis. What is the slope of the budget plan constraint?
