Question 5 (Essay Worth 5 points) Jessica purchased a DVD that was on sale for 12% off. The sales tax in her county is 3%. Let y
Vlad [161]

Answer:

<em>The expression for final cost of the DVD is  0.9064y</em>

Step-by-step explanation:

Jessica purchased a DVD that was on sale for 12% off.

If the original price of the DVD is  y , then the amount of discount on sale will be:  0.12y

So, the selling price of the DVD = (y-0.12y)= 0.88y

The sales tax in her county is 3%. So, the amount of sales tax on the selling price will be:  (0.88y\times 0.03)= 0.0264y

Thus, the expression for final cost of the DVD is:  (0.88y+0.0264y)= 0.9064y

Answer: Choice B) (24,10)

---------------------------------------------------------

Work Shown:

2x - 4y = 8
2( x ) - 4y = 8
2( 3y-6 ) - 4y = 8 ... notice x has been replaced with 3y-6
2(3y)+2(-6) - 4y = 8
6y-12 - 4y = 8
2y-12 = 8
2y-12+12 = 8+12 ... add 12 to both sides
2y = 20
2y/2 = 20/2 ... divide both sides by 2
y = 10

If y = 10, then
x = 3y-6
x = 3*10-6 ... replace y with 10
x = 30-6
x = 24

Put together, the solution is (x,y) = (24,10)
which is why the answer is choice B

As a check, we can plug (x,y) = (24,10) into each equation
x = 3y-6
24 = 3*10 - 6
24 = 30 - 6
24 = 24 ... true equation
and similarly for the second equation as well
2x-4y = 8
2*24 - 4*10 = 8
48 - 40 = 8
8 = 8 ... true equation
Both equations are true when (x,y) = (24,10) so the solution is confirmed
