Answer:
The retail price of the painting is $12750 .
Explanation:
As given
A gallery owner purchased a very old painting for $3,000.
The painting sells at a 325% increase in price .
325% is written in the decimal form.

= 3.25
Increase in the prize= 3.25 × 3000
= $9750
Retail price of the painting = Purchased cost of painting + Increase in the prize
= $9750 + $3000
= $12750
Therefore the retail price of the painting is $12750 .
