Jessica purchased a DVD that was on sale for 13% off. The sales tax in her county is 3%. Let v represent the original price of the DVD. Write an expression that can be used to determine the final cost of the DVD. (5 points)

.88v + .03v = final cost ——— .91v = the final cost

How to o figure it out.

100%-12% the the sale leaves 88% of v (,88y)

Then 3% tax (.03v)

.88v+.03v= .91v

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
