Jessica purchased a DVD that was on sale for 12% off. The sale tax in her country is 3%. Let y represent the original price of the DVD. Write an expression that can be used to determine the final cost of a DVD?

0.88%y + 0.03%

Step-by-step explanation:

if it's 12% then: she's actually paid 88% with a tax of 3%.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
