Astore is a 20% of a sale on all merchandise if maia buys one item and saves $13 what was the original price of her purchase

Step-by-step explanation:

20% of what number (x) is 13?

This is what we want. Now remember, 20% converted to decimal is:

20% = 20/100 = 0.20

Now translation the "word equation" above to algebraic equation is:

0.20 * x = 13

Note: "of" means "multiplication" and "is" means "equal to"

Now, let's solve for x (original price):

The original price is $65
