Final answer:
To find the profit-maximizing price and quantity of caps, set the marginal revenue equal to marginal cost. The profit-maximizing price is $120 and the quantity is 400 caps.
Step-by-step explanation:
To find the profit-maximizing price and quantity of caps, we need to equate the marginal revenue (MR) to the marginal cost (MC). The MR curve is the demand curve, which is given as p = 2400/√q. The MC is given as 6. We can find the profit-maximizing quantity by setting MR = MC:
2400/√q = 6
Solving for q, we get q = 400.
The profit-maximizing price can be found by substituting q = 400 into the demand curve:
p = 2400/√400 = 2400/20 = 120.
Therefore, the profit-maximizing price is $120 and the quantity is 400 caps.
