PLS ANSWER NOW WILL EARN BRAINLIEST IF RIGHT

Answer:
$250
Step-by-step explanation:
You can imagine the price of 212.5 to be 85% of the original price (100 - 15), so to do this, an easy way to find 100% is to simply divide the amount by the percentage:
Amount ÷ [tex]\frac{percentage}{100}[/tex]
Simply plug the values in:
212.50 ÷ ([tex]\frac{85}{100}[/tex]
= 250
So the price of the tablet before markdown was $250!
