A company has a monthly budget of x dollars. Every month, $20,700 of the monthly budget is spent on salaries. One-fifth of the remaining budget is spent on office supplies. Which function can be used to calculate the amount, in dollars, spent on office supplies?

There are situations in real life where some variables depend on other(s) and that dependency can be determined as a practical rule or from a well-known theory. The expression who relates those variables are commonly called functions and they become a very useful tool to analyze, explain and predict the behavior of such events.

We know the monthly budget of a company is x dollars. $20,700 out of it is spent on salaries. After deducting salaries, the remaining budget is

[tex]x-20,700[/tex]

One-fifth of it is spent on office supplies, so the required function is

[tex]OS=\frac{1}{5}(x-20,700)[/tex]

[tex]OS=\frac{x-20,700}{5}[/tex]

Answer: Amount spent on office supplies can be calculated as this: $(1/5 × (x — 20,700).

Step-by-step explanation:

Step 1:

Let Monthly Budget of the Company, M = $x

Amount spent on salaries, S = $20,700

Step 2:

To get balance of the budget, R. Subtract S from M

Therefore,

Remaining balance of the budget, R = $(x — 20,700)

Step 3:

Amount spent on office supplies O is given as 1/5 of balance of the budget. I.e, O = 1/5 × R

Therefore, O = $(1/5 × (x — 20,700).
