Question 182361
The amount of gold jewelry and other products is measured in karats (K), where 24K represents pure gold. The mark 14K on a chain indicates that the ratio between the mass of the gold in the chain and the mass of the chain is 14:24. If a gold ring is marked 18K and it weighs 0.4 oz, what is the value of the gold ring if pure gold is valued at $300 per oz?
:
{{{18/24}}} * .4 * 300 = $90.00
