(a)
New selling price after 10% discount
= 100% - 10%
= 90%
Price of the study table after Easter discount
= 90% x 360
=
95100 x 360
= $324.00
New selling price after 5% further discount
= 100% - 5%
= 95%
Price of the study table after credit card discount
= 95% x 324.00
=
95100 x 324.00
= $307.80
Price to pay after including GST
= 100% + 6%
= 106%
Price of the study table after GST
= 106% x 307.80
=
106100 x 307.80
≈ $326.27 (Round off to nearest cent)
(b)
Price of the study table after cash discount
= 324.00 - 30
= $294.00
Price of the study table after GST
= 106% x 294.00
=
106100 x 294.00
≈ $311.60 (Round off to nearest ten cent)
Answer(s): (a) $326.27; (b) $311.60
