(a)
New selling price after 30% discount
= 100% - 30%
= 70%
Price of the study table after Easter discount
= 70% x 2000
=
90100 x 2000
= $1400.00
New selling price after 10% further discount
= 100% - 10%
= 90%
Price of the study table after credit card discount
= 90% x 1400.00
=
90100 x 1400.00
= $1260.00
Price to pay after including GST
= 100% + 7%
= 107%
Price of the study table after GST
= 107% x 1260.00
=
107100 x 1260.00
≈ $1348.20 (Round off to nearest cent)
(b)
Price of the study table after cash discount
= 1400.00 - 55
= $1345.00
Price of the study table after GST
= 107% x 1345.00
=
107100 x 1345.00
≈ $1439.20 (Round off to nearest ten cent)
Answer(s): (a) $1348.20; (b) $1439.20
