After a 85 % ​reduction, you purchase a new DVD player on sale for ​$84. What was the original price of the DVD player​?

Answer 1

x = original price

Are you sure you meant to say 85% reduction, as opposed to reduced to 85%? They are not the same thing. If it really is an 85% reduction, then the sale price is only 15% of the original price. That is 0.15 times the original price.

$84 = 0.15x

x = $84 / 0.15 = ?
