I Need Help With This Problem. How To Find The Answer. Thanks?
Written by Admin on September 8, 2009The invoke of antimonial adornment and added products is rhythmic in karats, where 24k represents decent gold. The assessment 14k on a anxiety indicates that the ratio between the accruement of the antimonial in the anxiety and the accruement of the anxiety is 14:24. If a gold ring is blemished 18k and it weights 0.4oz, what is the activity of the antimonial in the anulus if decent antimonial is valued at $300 per oz?

In an 18k ring, the ratio of gold is 18:24 which reduces to 3:4
Take 3/4 of 0.4 to get 0.3 oz. of gold.
Multiply this by the price per oz. ($300).
0.3 x $300 = $90
Answer:
$90

amount of gold in chain = 18/24 * 0.4 = 0.3 oz
value of gold = $ 0.3 * 300 = $ 90
