The county government released $100,000 as an appropriation for a counseling program for at-risk teenagers. The program should run one year and the variable costs for the program are $400 per teenager per year. Within the relevant range of 50 to 150 teenagers, the fixed costs for the program are $60,000. How many teenagers can the program serve

Number of teenagers= 100 teenager

Explanation:

Giving the following information:

The county government released $100,000 as an appropriation for a counseling program for at-risk teenagers. The variable costs for the program are $400 per teenager per year. Within the relevant range of 50 to 150 teenagers, the fixed costs for the program are $60,000.

First, we need to deduct the fixed costs that remain don't affect directly the teenagers.

Budget= 100,000 - 60,000= 40,000

Now, we can calculate the number of teenagers to attend:

Number of teenagers= 40,000/400= 100 teenagers

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.'
