Discount based on the storewide 20% promotion
= 20% x 1600
=
20100 x 1600
= $320
Amount that Adam has to pay after 20% promotion
= 1600 - 320
= $1280
Further discount after another 10% discount
= 10% x 1280
=
10100 x 1280
= $128
Amount that Adam pays for the stereo system in all
= 1280 - 128
= $1152
Answer(s): $1152
