Hi there!
So, here’s the important information we know:

20% of X = 15

The word “of” is the same thing as a multiplication sign, so let’s see the equation like this instead:

20% × X = 15

20% is the same thing as 20 ÷ 100, which is equal to 0.2

0.2 × X = 15

Solving the equation :

0.2 × X = 15

Divide each side of the equation by 0.2

X = 75


So your answer is: The regular price of the shoes before the 20% coupon was applied is $75!

There you go! I really hope this helped, if there’s anything just let me know! ☻
