(a)
New selling price after 25% discount
= 100% - 25%
= 75%
Price of the kitchen table after National Day discount
= 75% x 400
=
95100 x 400
= $300.00
New selling price after 5% further discount
= 100% - 5%
= 95%
Price of the kitchen table after credit card discount
= 95% x 300.00
=
95100 x 300.00
= $285.00
Price to pay after including GST
= 100% + 6%
= 106%
Price of the kitchen table after GST
= 106% x 285.00
=
106100 x 285.00
≈ $302.10 (Round off to nearest cent)
(b)
Price of the kitchen table after cash discount
= 300.00 - 40
= $260.00
Price of the kitchen table after GST
= 106% x 260.00
=
106100 x 260.00
≈ $275.60 (Round off to nearest ten cent)
Answer(s): (a) $302.10; (b) $275.60
