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