If it is known that the book value of the printer is $15,000 in 2014, what is the scrap value of this printer? 2. At a unit price of $5, consumers in College Station will demand 15,000 Maroon Out T-Shirts. But for each $1 increase in price, they will demand 2,000 fewer T-shirts. The suppliers of the Maroon Out T-Shirts will not produce any T-shirts if the selling price is $3 or less, but at a unit price of $8, they are willing to supply 30,000 T-shirts. What is the market equilibrium for Maroon Out T-shirts?
