Phil sells duck calls in a perfectly competitive market. if duck calls sell for $10 each and average total cost per unit is $11 at the profit-maximizing output level, then in the long runa. more firms will enter the market. b. some firms will exit from the market. c. the equilibrium price per duck call will fall. d. average total costs will fall.

a. more firms will enter the market.

Step-by-step explanation:

In the short term, there is economic loss. The price is $10 and the average cost is $11, meaning that every unit sold has a loss of one dollar. Registration and withdrawal is open when there is a long-term, and loss-making units can leave the market. This will lower the supply and raise the market price, but the cost of production will not change.

Hence some firm will leave the market

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
