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

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

Given parallelogram ABCD, diagonals AC and BD intersect at point E. AE=2x, BE=y+10, CE=x+2 and DE=4y−8. Find y.

hodyreva [135]

Answer:

B. 6

Step-by-step explanation:

The diagonals of a parallelogram intersect at their midpoints, so ...

DE = BE

4y -8 = y +10

3y = 18 . . . . . . . add 8-y

y = 6 . . . . . . . . divide by 3

<em>Additional comment</em>

The value of x is found the same way:

2x = x+2 ⇒ x = 2
