Answer: Amount he saved is $17.64.
Explanation:
Let the actual price of each game be 'x'.
Let the actual price of security program be 'y'.
Since we have given that
Games are marked down by 15%.
Security programs are marked down by 18%.
Amount paid by him on each game = $35.70
So, Amount paid by him on two games = 35.70 × 2 = $71.4
So, Price of games becomes,

Similarly,
Amount of security program paid by him = $22.96
So, Cost of security program is given by

Hence, Original price of games and security program is $84+$28=$112.
total amount he paid is given by
71.40+22.96=$94.36
So, Amount he saved is given by
Original price - Amount paid
$112-$94.36
=$17.64
