Math Problem Statement
You can sell 150 pet chias per week if they are marked at $1 each, but only 120 each week if they are marked at $2/chia. Your chia supplier is prepared to sell you 30 chias each week if they are marked at $1 per chia, and 100 each week if they are marked at $2 per chia. (a) Write down the associated linear demand and supply functions. demand function q(p) =
supply function q(p) =
(b) At what price (in dollars) should the chias be marked so that there is neither a surplus nor a shortage of chias?
