A software store has put some of its inventory on sale. Games are marked down by 15%, and security programs are marked down by 1

Katyanochek1 [597]

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

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