Answer:
$480
Step-by-step explanation:
Hello!
Luke buys a TV 25% off of the original price, or 75% of the original price.
The original price is 100%, and 75% of the price is the original price minus $120.
Let the original price be x:
[tex]1x = 0.75x + 120\\\\0.25x = 120\\\\0.25x * 4 = 120 * 4\\\\x = 480[/tex]
The original price of the TV is 480. We can double-check our answer:
[tex]0.75(480) + 120 = 1(480)\\\\ 360 + 120 = 480\\\\480 = 480[/tex]
The original price is $480
