What is his inverse demand curve for earplugs? (Implicitly, the price of money left over for other goods is 1)

If the price of earplugs is $50, how many earplugs will he consume?

If the price of earplugs is $80, how many earplugs will he consume?

Suppose that Quasimodo has $4,000 in total to spend a month. What is his total utility for earplugs and money to spend on other things if the price of earplugs is $50?

What is his total utility for earplugs and other things if the price of earplugs is $80?
