(a)
New selling price after 20% discount
= 100% - 20%
= 80%
Price of the breakfast hutch after Easter discount
= 80% x 520
=
90100 x 520
= $416.00
New selling price after 10% further discount
= 100% - 10%
= 90%
Price of the breakfast hutch after credit card discount
= 90% x 416.00
=
90100 x 416.00
= $374.40
Price to pay after including GST
= 100% + 5%
= 105%
Price of the breakfast hutch after GST
= 105% x 374.40
=
105100 x 374.40
≈ $393.12 (Round off to nearest cent)
(b)
Price of the breakfast hutch after cash discount
= 416.00 - 30
= $386.00
Price of the breakfast hutch after GST
= 105% x 386.00
=
105100 x 386.00
≈ $405.30 (Round off to nearest ten cent)
Answer(s): (a) $393.12; (b) $405.30
