A manufacturer sells 50 boats per month at $25000 per boat, and each month demand is increasing at a rate of 4 boats per month. What is the fastest you could drop your price before your monthly revenue starts to drop

For the revenue per month to drop, the price per boat per month has to drop more than $2,000

Explanation:

Given:

Number of boats sold per month = 50

Cost of each boat = $25,000

Each month demand increases at a rate of 4 boats per month.

Required:

Find the fastest price could drop before monthly revenue starts to drop.

Revenue, R = Price × Quantity

R = P × Q

Differntiate both sides with respect to time, t:

For the fastest price could drop before monthly revenue starts to drop,

Thus,

Since the answer is negative, it indicates a drop in price.

Therefore, for the revenue per month to drop, the price per boat per month has to drop more than $2,000

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
