(a)
New selling price after 25% discount
= 100% - 25%
= 75%
Price of the dining table after Chinese New Year discount
= 75% x 1250
=
85100 x 1250
= $937.50
New selling price after 15% further discount
= 100% - 15%
= 85%
Price of the dining table after credit card discount
= 85% x 937.50
=
85100 x 937.50
= $796.88
Price to pay after including GST
= 100% + 9%
= 109%
Price of the dining table after GST
= 109% x 796.88
=
109100 x 796.88
≈ $868.60 (Round off to nearest cent)
(b)
Price of the dining table after cash discount
= 937.50 - 25
= $912.50
Price of the dining table after GST
= 109% x 912.50
=
109100 x 912.50
≈ $994.60 (Round off to nearest ten cent)
Answer(s): (a) $868.60; (b) $994.60
