The original price is 100% of the original price since 100% is a whole amount.
When you apply a 35% discount, since 100% - 35% = 65%, the final, discounted price is 65% of the original price.
Let x = the original price
65% of x = $26.59
0.65x = $26.59
Divide both sides by 0.65
x = $40.9076...
Answer: The original price is $40.91
