Answer 1

Given:

A person earns Php 390.00 per day in a certain job.

To determine:

To express the total salary (S) as a function of the number of days the person works (n).

To be recollected:

• Php: Php denotes the currency of Philippines, "Philippine Peso".

• Function: Function is a relation that associates an element of one set to an element of other set, i.e., an element, called as the "domain element" is expressed in terms of other element.

Step-by-step explanation:

As given in the question,

• Salary of the person per day = $390.00$

• Total salary is denoted by "S".
• Number of days worked by the person is denoted by "n".

Considering an example, "The cost of one pen is Rs.10 in a store. Then the cost 10 similar pens will be":

$= cost of one pen * number of pens\\= 10*10\\=Rs.100$

In the similar manner, the data given in the question can be processed as follows:

Salary for "n" number of days, if the one day's salary is 390.00, is given by:

$S= one day's salary * number of days\\S=390 * n\\S=390(n)$

∴ The required total salary is expressed as: $S=390(n)$
