Answer:
$325
Step-by-step explanation:
if the refrigerator has been marked UP by 25%, this means that $406.25 is 125% of the original price (the original price being 100%).
Therefore, divide 406.25 by 125 to find the cost per 1%, then multiply by 100 to find the original price.
(406.25 ÷ 125) x 100 = 325
