The price of a printer with 15% GST is $1840.
- How much does Adam have to pay if the GST is decreased to 9%?
- How much saving does Adam enjoy as a result of the decrease in GST?
(a)
Price of the printer with 15% GST
= 100% + 15%
= 115%
115% → $1840
1% → 1840 ÷ 115 = $16
100% → 100 x 16 = $1600
Price of the printer with 9% GST
= 100% + 9%
= 109%
Amount that Adam has to pay
= 109% x 1600
=
109100 x 1600
= $1744
(b)
Saving that Adam enjoys
= 1840 - 1744
= $96
Answer(s): (a) $1744; (b) $96
