The price of a printer with 5% GST is $7560.
- How much does Adam have to pay if the GST is increased to 9%?
- How much more must Adam pay because of the GST increase?
(a)
Price of the printer with 5% GST
= 100% + 5%
= 105%
105% → $7560
1% → 7560 ÷ 105 = $72
100% → 100 x 72 = $7200
Price of the printer with 9% GST
= 100% + 9%
= 109%
Amount that Adam has to pay
= 109% x 7200
=
109100 x 7200
= $7848
(b)
Amount more that Adam must pay because of the GST increase
= 7848 - 7560
= $288
Answer(s): (a) $7848; (b) $288
