(a)
New selling price after 25% discount
= 100% - 25%
= 75%
Price of the breakfast hutch after Mother's Day discount
= 75% x 380
=
95100 x 380
= $285.00
New selling price after 5% further discount
= 100% - 5%
= 95%
Price of the breakfast hutch after credit card discount
= 95% x 285.00
=
95100 x 285.00
= $270.75
Price to pay after including GST
= 100% + 9%
= 109%
Price of the breakfast hutch after GST
= 109% x 270.75
=
109100 x 270.75
≈ $295.12 (Round off to nearest cent)
