On November 1, Year 1, an entity sold 50 machines to a customer for $100 each. The cost of each machine is $20. The entity allows customers to return any unused machine within 6 months and receive a full refund. The entity uses the expected value method to estimate the variable consideration. Based on the entity’s experience and other relevant factors, it reasonably estimates that 10 machines (6 in Year 1 and 4 in Year 2) will be returned. What amount of revenue is recognized by the entity from the sale of these machines on November 1, Year 1?

$4400

Explanation:

The following information can be gotten from the question:

Number of machine sold = 50

Cost of each machine = $20

Amount sold per machine to the customer = $100

We are also informed that based on the experience of the entity and other factors, it estimates that 10 machines which are 6 in Year 1 and 4 in Year 2 will be returned.

The amount of revenue is recognized by the entity from the sale of these machines on November 1, Year 1 will be the number of machine sold minus the expected machine to be returned for year 1 which is then multiplied by the unit sales price. This can be mathematically written as:

=(50-6) × $100

= 44 × $100

=$4400

The answer is $4400

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.'
