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: $(0.88y+0.0264y)= 0.9064y$
