Answer 2

Option D.
`\$11.34`

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`

`100\%-18\%=82\%=82\100=0.82`

The total pay with discount is

`\$35.70+\$22.96=\$58.66`

we have that

`0.85(2x)=35.70\\1.70x=35.70\\x=\$21`

`0.82y=22.96\\y=\$28`

Find the total pay without discount

`2x+y=2(21)+28=\$70`

The amount saved is the difference

`\$70-\$58.66=\$11.34`
