The regular price was ​$
nothing.
​(Round to the nearest​ cent, if​ necessary.)

Answer 1

$140.35

Explanation:

35% sale means 100-35 = 65% of the cost was paid

65% : $91.23

100% : X

X/100 = 91.23/65

X = 140.3538462

Answer 2

$140.35

Explanation:

Say the regular price was x. Then subtracting 35% of x from x, we get the discounted price of $91.23. We can model this with the equation:

x - 35% * x = 91.23

Remember that % simply means "out of 100", so 35% = 35/100 = 0.35:

x - 0.35x = 91.23

0.65x = 91.23

x = 140.35

So, the regular price was $140.35.

Hope this helps!
