Discount based on the storewide 10% promotion
= 10% x 1000
=
10100 x 1000
= $100
Amount that Adam has to pay after 10% promotion
= 1000 - 100
= $900
Further discount after another 3% discount
= 3% x 900
=
3100 x 900
= $27
Amount that Adam pays for the stereo system in all
= 900 - 27
= $873
Answer(s): $873
