Question

Assume your salary is $24,000 per year and $50 for each computer you sell. What function represents your total pay for one year? Be sure to indicate any domain restrictions.

Answer 1

Let x represent the total amount of computers you sell in one year.

Since you get $50 for each computer, then, you would get 50x for x computers.

Additionally, your base salary is $24,000. Then, add 50x and 24,000 to find your total salary in a year.

If f(x) is a function that represents your salary depending on the amount of computers you sell, then:

`f(x)=50x+24000`

Notice that the amount of computers that you sell cannot be a negative number. Then, you must take into account the following restriction:

`x\ge0`

Therefore, the answer is:

`f(x)=50x+24000\text{ for }x\ge0`
