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 15% discount
= 15% x 900
=
15100 x 900
= $135
Amount that Adam pays for the mobile phone in all
= 900 - 135
= $765
Answer(s): $765
