Answer:
$544
Step-by-step explanation:
To determine the original price of the DVD player considering that you know that it had a 75% reduction, you can use a rule of three as the price of $136 represents 25% of the original price and with this you can calculate the price that represents 100%:
$136 → 25%
x ← 100%
x=(136*100)/25=$544
According to this, the answer is that the original price of the DVD player was $544.
