Answer:
Option D. ![\$11.34](https://tex.z-dn.net/?f=%5C%2411.34)
Step-by-step explanation:
Let
x -----> the original price of one game
y ----> the original price of one security programs
Remember that
![100\%-15\%=85\%=85\100=0.85](https://tex.z-dn.net/?f=100%5C%25-15%5C%25%3D85%5C%25%3D85%5C100%3D0.85)
![100\%-18\%=82\%=82\100=0.82](https://tex.z-dn.net/?f=100%5C%25-18%5C%25%3D82%5C%25%3D82%5C100%3D0.82)
The total pay with discount is
![\$35.70+\$22.96=\$58.66](https://tex.z-dn.net/?f=%5C%2435.70%2B%5C%2422.96%3D%5C%2458.66)
we have that
![0.85(2x)=35.70\\1.70x=35.70\\x=\$21](https://tex.z-dn.net/?f=0.85%282x%29%3D35.70%5C%5C1.70x%3D35.70%5C%5Cx%3D%5C%2421)
![0.82y=22.96\\y=\$28](https://tex.z-dn.net/?f=0.82y%3D22.96%5C%5Cy%3D%5C%2428)
Find the total pay without discount
![2x+y=2(21)+28=\$70](https://tex.z-dn.net/?f=2x%2By%3D2%2821%29%2B28%3D%5C%2470)
The amount saved is the difference
![\$70-\$58.66=\$11.34](https://tex.z-dn.net/?f=%5C%2470-%5C%2458.66%3D%5C%2411.34)
