(a)
New selling price after 20% discount
= 100% - 20%
= 80%
Price of the breakfast hutch after Mother's Day discount
= 80% x 460
=
85100 x 460
= $368.00
New selling price after 15% further discount
= 100% - 15%
= 85%
Price of the breakfast hutch after credit card discount
= 85% x 368.00
=
85100 x 368.00
= $312.80
Price to pay after including GST
= 100% + 5%
= 105%
Price of the breakfast hutch after GST
= 105% x 312.80
=
105100 x 312.80
≈ $328.44 (Round off to nearest cent)
(b)
Price of the breakfast hutch after cash discount
= 368.00 - 95
= $273.00
Price of the breakfast hutch after GST

=
105100 x 273.00
≈ $286.70 (Round off to nearest ten cent)
