Suppose that Sears has a sale on a portable DVD player. The DVD player was originally $80. However, the DVD player was marked down at a 25% discount, but today Sears is
having a special 25% off everything in the store, even sales items. What would the cost of the item be today after both discounts? (Explain how you got your answer)

The answer would be $40.

Step-by-step explanation:

You take the first 25% off and add it to the other 25% off, which would equal 50% off. After that you take 50% off for $80, which would be $40 because half of $80 is $40.

the infinity sign

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16
