Charlize Gardner · Answer 1

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

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

Kyan Nguyen · Answer 2

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
