Adam wants to buy a stereo system. The usual price of the stereo system is $2100.
As a privileged card member, he is entitled to a discount of 50%.
He needs to pay a GST of 4%.
- How much is the GST?
- How much does he pay for the stereo system in all?
Discount
= 50% x 2100
=
50100 x 2100
= $1050
Amount that Adam has to pay
= 2100 - 1050
= $1050
GST
= 4% x 1050
=
4100 x 1050
= $42
(b)
Amount that Adam pays for the stereo system in all
= 1050 + 42
= $1092
Answer(s): (a) $42; (b) $1092
