Discount based on the storewide 30% promotion
= 30% x 300
=
30100 x 300
= $90
Amount that Adam has to pay after 30% promotion
= 300 - 90
= $210
Further discount after another 10% discount
= 10% x 210
=
10100 x 210
= $21
Amount that Adam pays for the computer in all
= 210 - 21
= $189
Answer(s): $189
