Adam wants to buy a hi-fi system. The usual price of the hi-fi system is $1600.
As a privileged card member, he is entitled to a discount of 20%.
He needs to pay a GST of 10%.
- How much is the GST?
- How much does he pay for the hi-fi system in all?
Discount
= 20% x 1600
=
20100 x 1600
= $320
Amount that Adam has to pay
= 1600 - 320
= $1280
GST
= 10% x 1280
=
10100 x 1280
= $128
(b)
Amount that Adam pays for the hi-fi system in all
= 1280 + 128
= $1408
Answer(s): (a) $128; (b) $1408
