Discount based on the storewide 30% promotion
= 30% x 2000
=
30100 x 2000
= $600
Amount that Adam has to pay after 30% promotion
= 2000 - 600
= $1400
Further discount after another 10% discount
= 10% x 1400
=
10100 x 1400
= $140
Amount that Adam pays for the stereo system in all
= 1400 - 140
= $1260
Answer(s): $1260
