The custom T-shirt printing business has many competitors, so that the perfect competition model may be con- sidered a good approximation. Currently the market demand curve is given by Q = 120 − 1.5 p, whereas the market supply is given by Q = −20 + 2 p.
(a) Determine the market equilibrium
suppose there is an in- crease in the cost of blank T-shirts, an essential input into the business of selling custom T-shirts. Specifically, for each unit by each supplier, the production cost goes up by 10%.
(b) Determine the new supply curve.
(c) Determine the change in equilibrium price.
(d) If your answer to the previous question is different from 10%, explain the difference in values.
