Option 2 (Step-by-step method): Step 1: Calculate the tax increase amount. Use the
Basic Percentage Calculator (“What is A% of B?”). Enter
5 [A] and $
300 [B]. The calculator will determine
5% of $

Formula explanation:
We want to find the new tax amount after a
5% increase from $
300.
Amount of increase =
5% of $
300
Amount of increase = (
5 / 100) × $
300 = 0.05 × $
300 = $
15
New tax amount = Previous tax amount + Amount of increase
New tax amount
= $
300 + $
15 = $
315
