(a)
New selling price after 15% discount
= 100% - 15%
= 85%
Price of the breakfast hutch after Mother's Day discount
= 85% x 2500
=
90100 x 2500
= $2125.00
New selling price after 10% further discount
= 100% - 10%
= 90%
Price of the breakfast hutch after credit card discount
= 90% x 2125.00
=
90100 x 2125.00
= $1912.50
Price to pay after including GST
= 100% + 6%
= 106%
Price of the breakfast hutch after GST
= 106% x 1912.50
=
106100 x 1912.50
≈ $2027.25 (Round off to nearest cent)

Price of the breakfast hutch after cash discount

=
106100 x 2055.00
≈ $2178.30 (Round off to nearest ten cent)
