Question

Before tax, the price of fuel is $3.40 per liter. Tax of 20% is added. Work out the cost of 28 liters of fuel including tax.

Answer 1

Answer:

1 L costs $3.40

28 L will cost 28 × 3.40

Tax on 28 × 3.40 will be 28×3.40 × 0.2

So total cost will be 28×3.4 + 28×3.4×0.2

=28×3.4(1+0.2) = 28×3.4×1.2

Multiply these three, you will get the answer
