Question

. A person is earning ₱500.00 per day for doing a certain job. Which of the following expresses the total salary S as a function of the number n of days that the person works? a. () = 500 + b. () = 500 c. () = 500 d. () = 500 − l

Answer 1

Given:

Given that, a person is earning ₱500 per day for doing a certain job.

To find:

We need to find a function (the total salary $S$) of the number $n$ number of days that the person works.

Solution:

Let the required function is $S(n)$.

According to the question, a person is earning ₱500 per day for doing a certain job.

If the person does the job for 2 days, he gets ₱1000.

So, to write the function of total salary $S(n)$, multiply the earnings per day and the number of days that person works.

So,

$\Rightarrow S(n)=500\times n$

$\Rightarrow S(n)=500n$

Therefore, the required function is $S(n)=500n$, where $n$ represents numbers of days worked.
