1.The market for manicures and other nail treatments is very competitive. How would the following developments affect the number of nail treatments that a typical nail salon wants to supply in the short run?

a. Heightened concern about their appearance causes people to want more manicures at a given price.

b. The government requires all nail salons to pay a new yearly licensing fee to operate.

c. Worse job prospects elsewhere in the economy cause more people to want to become manicurists, causing the wages of manicurists to fall.
