Apet store owner set the price of a bag of cat food at 50% above the cost. when it did not sell, the price was reduced by 20%, to $12.00. what was the original cost?

$10.

Step-by-step explanation:

Let x represent the original cost of bag of cat food.

We have been given that a pet store owner set the price of a bag of cat food at 50% above the cost. So the cost of cat food would be x plus 50% of x.

We are further told that the price was reduced by 20%, when it did not sell. So price of cat food after reduction would be minus 20 percent of .

Since price after reduction was $12, so we will equate with 12 as:

Therefore, the original cost of cat food was $10.
