(a)
New selling price after 30% discount
= 100% - 30%
= 70%
Price of the kitchen table after Mid Year discount
= 70% x 1600
=
85100 x 1600
= $1120.00
New selling price after 15% further discount
= 100% - 15%
= 85%
Price of the kitchen table after credit card discount
= 85% x 1120.00
=
85100 x 1120.00
= $952.00
Price to pay after including GST
= 100% + 5%
= 105%
Price of the kitchen table after GST
= 105% x 952.00
=
105100 x 952.00
≈ $999.60 (Round off to nearest cent)
(b)
Price of the kitchen table after cash discount
= 1120.00 - 90
= $1030.00
Price of the kitchen table after GST
= 105% x 1030.00
=
105100 x 1030.00
≈ $1081.50 (Round off to nearest ten cent)
Answer(s): (a) $999.60; (b) $1081.50
