I have a math problem, and need help. If I bought a half an ounce of gold for $500 and sold .3 gr. ?

Question

How much is the actual price that I buy the .3 gr out of the 14 grams that equals a half of an ounce?

Answer 1

Gold is sold by the troy ounce, 31.1 grams / troy ounce.

If you paid $500 for 15.55 grams, you paid $32.258 per gram.

.3 gr = $9.67

Answer 2

500/14=35.714285 x 3=107.14285 rounded to nearest $ would be $107
