To determine

The bus tickets in Alphonso ‘s town has increased to $1 per trip whereas the price of burger is constant at $2 and his income is $10 per week. Provide Alphonso’s new budget constraint. Also, comment about the opportunity cost of bus tickets.

Answer to Problem 1SCQ

As the price of bus tickets rises, the opportunity cost of bus tickets falls.

Explanation of Solution

The equation of budget constraint is:



PBT= Price of Bus TicketQBT=Quantity of Bus TicketPB= Price of BurgerQB= Quantity of BurgerI = Income 

Therefore, the equation of new budget constraint will be as follows:

$1×QBT+ $2×QB= 10

The formula for opportunity cost of bus tickets would be:

Δ Price of BurgersΔ Price of Bus tickets

So, as the price of bus tickets rises, the opportunity cost of bus tickets falls.
