Adam wants to buy a projector. The usual price of the projector is $900.
As a privileged card member, he is entitled to a discount of 50%.
He needs to pay a GST of 2%.
- How much is the GST?
- How much does he pay for the projector in all?
Discount
= 50% x 900
=
50100 x 900
= $450
Amount that Adam has to pay
= 900 - 450
= $450
GST
= 2% x 450
=
2100 x 450
= $9
(b)
Amount that Adam pays for the projector in all
= 450 + 9
= $459
Answer(s): (a) $9; (b) $459
