You run a hospital with 100 rooms. fixed daily cost is $880.00 which includes staff salary, property charges, maintenance etc. variable cost per room is $11.00 which includes cleaning, equipment rentals, utility cost etc. which is incurred only when the room is full. you charge $55.00 per room per day. you sold 41.00 rooms today, how much profit/loss did you earn for today?

$924

Explanation:

The computation of the profit/loss is shown below:

= Sale - variable cost - fixed daily cost

where,

Sale = Selling price per room × Number of rooms sold

= $55 × 41 rooms

= $2,255

And, the variable cost would be

= Variable cost per room × Number of rooms sold

= $11 × 41 rooms

= $451

And, the fixed daily cost is $880

Now put these values to the above formula

So, the value would be equal to

= $2,255 - $451 - $880

= $924

and whats your questoin

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.'
