The assessment 14k on a anxiety indicates that the allot 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 weighs 0.4 oz, what is the activity of the antimonial in the anulus decent antimonial is valued at $300 per oz?

THe ring contains 18/24 = 3/4 gold
so the gold’s weight = 3/4 x 0.4 = 0.3 oz
so it’s value = 0.3 x $300 = $90

Value = (18 oz Gold / 24 oz Chain) * (0.4 oz Chain) * ($300 / oz Gold)
Value = (18/24) * 0.4 * 300 = (3/4) * 0.4 * 300 = $90

18/24 = 3/4 gold * .4 oz * $300/oz = 3/4 * $120 = $90
