The price of a projector with 2% GST is $1530.
- How much does Adam have to pay if the GST is increased to 10%?
- How much more must Adam pay because of the GST increase?
(a)
Price of the projector with 2% GST
= 100% + 2%
= 102%
102% → $1530
1% → 1530 ÷ 102 = $15
100% → 100 x 15 = $1500
Price of the projector with 10% GST
= 100% + 10%
= 110%
Amount that Adam has to pay
= 110% x 1500
=
110100 x 1500
= $1650
(b)
Amount more that Adam must pay because of the GST increase
= 1650 - 1530
= $120
Answer(s): (a) $1650; (b) $120
