A firm produces red and blue bobbleheads. It can sell red bobbleheads for $20 - Qr /2000 a piece
And blue bobbleheads for $17 - Qb/2000 a piece
Where Qr = red bobbleheads per week
Qb = ble bobbleheads per week
The total cost of producing Q = Qr + Qb bobbleheads is 4Q + Q^2/4000.
What are the profit maximizing quantities of red and blue bobbleheads for this firm to make and sell?
