The price of a tablet with 5% GST is $3780.
- How much does Adam have to pay if the GST is increased to 6%?
- How much more must Adam pay because of the GST increase?
(a)
Price of the tablet with 5% GST
= 100% + 5%
= 105%
105% → $3780
1% → 3780 ÷ 105 = $36
100% → 100 x 36 = $3600
Price of the tablet with 6% GST
= 100% + 6%
= 106%
Amount that Adam has to pay
= 106% x 3600
=
106100 x 3600
= $3816
(b)
Amount more that Adam must pay because of the GST increase
= 3816 - 3780
= $36
Answer(s): (a) $3816; (b) $36
