Adam wants to buy a printer. The usual price of the printer is $900.
As a privileged card member, he is entitled to a discount of 20%.
He needs to pay a GST of 5%.
- How much is the GST?
- How much does he pay for the printer in all?
Discount
= 20% x 900
=
20100 x 900
= $180
Amount that Adam has to pay
= 900 - 180
= $720
GST
= 5% x 720
=
5100 x 720
= $36
(b)
Amount that Adam pays for the printer in all
= 720 + 36
= $756
Answer(s): (a) $36; (b) $756
