1 game 15%
1 security program 18%
15% of 35.70 = $5.4 with 2 games you saved $10.8 so far
18% of 22.96 = $4.1 + 10.8 = $14.9
1 security program 18%
15% of 35.70 = $5.4 with 2 games you saved $10.8 so far
18% of 22.96 = $4.1 + 10.8 = $14.9
Answer: Amount he saved is $17.64.
Step-by-step 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,
[tex]\frac{85}{100}\times x=\$71.4\\\\x=71.4\times \frac{100}{85}\\\\x=\$84[/tex]
Similarly,
Amount of security program paid by him = $22.96
So, Cost of security program is given by
[tex]\frac{100-18}{100}\times y=\$22.96\\\\\frac{82}{100}\times y=\$22.96\\\\y=\frac{100}{82}\times 22.96\\\\y=28[/tex]
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
