Calculating GST (HSC SSCE Mathematics Standard): Flashcards

Goods and Services Tax

$10$

Basic food items and certain medical expenses

$\text{GST} = 0.10 \times \text{pre-tax price}$

$\text{Total cost} = 1.10 \times \text{pre-tax price}$

$1.10$ or $110\%$

$\text{Pre-tax price} = \text{Total cost} \div 1.10$

Divide by $1.10$, not $0.10$

Value Added Tax

$2\%$ to $25\%$
