The price of a printer with 5% GST is $9240.
- How much does Adam have to pay if the GST is increased to 11%?
- How much more must Adam pay because of the GST increase?
(a)
Price of the printer with 5% GST
= 100% + 5%
= 105%
105% → $9240
1% → 9240 ÷ 105 = $88
100% → 100 x 88 = $8800
Price of the printer with 11% GST
= 100% + 11%
= 111%
Amount that Adam has to pay
= 111% x 8800
=
111100 x 8800
= $9768
(b)
Amount more that Adam must pay because of the GST increase
= 9768 - 9240
= $528
Answer(s): (a) $9768; (b) $528
