Answer 2

Answer:

Option D. $\ 11.34$

Step-by-step explanation:

Let

x -----> the original price of one game

y ----> the original price of one security programs

Remember that

$100\%-15\%=85\%=85\100=0.85$

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

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

$\ 70-\ 58.66=\ 11.34$
