x = list price = price before discount
15% is the discount, ie, we take 15% of x and subtract it off the original price
final price = (original price) - (15% of original price)
final price = x - 15% of x
final price = x - 0.15x
final price = 0.85x
The final price (or sale price) is $722.50, therefore
0.85x = 722.50
0.85x
/0.85
= 722.50/0.85
x = 850
