Budget constraints can show opportunity costs if your budget is $10 and you can buy 5 burgers at $2 each or 20 bus tickets at $.50 each it is pretty easy to calculate the opportunity cost.

Simplify first for every 1 burger is worth 4 bus tickets.

Calculate the opportunity costs of eating a burger = 4 bus tickets/1 burger = 4 bus tickets, so any time I decide to spend money on one more burger I have to give up the opportunity of 4 bus tickets.

Calculate the opportunity cost of taking the bus, use the same math above. Put the answer below:

the opportunity cost of a bus ticket is 1 burger

the opportunity cost of a bus ticket is .25 of a burger

the opportunity cost of a bus ticket is .50 of a burger

the opportunity cost of a bus ticket is 2 burgers
