If the TV is 70% off, then that means she paid 30% of the original cost. If 30% of the original cost is $120, then...

30% * x = 120
.30x = 120
x = 120/.30
x = 400

The original cost was $400

Original price x (100-70)/100 = $120

therefore; original price = 120 × 100/30 = $400

A percentage change is computed as follows:

percent change = ((new value) -(original value))/(original value) × 100%

For your first one, this looks like ...

percent change = ($25 -$75)/$75 × 100% = (-50/75) × 100% = -0.667×100%

percent change = -66.7%

When there are a lot of similar calculations to do, I like to use a spreadsheet. See below for the other percentage changes (rightmost column).
