To find the weight of the gold coin, you can use the following formula:
\[ \text{Weight of the coin (in ounces)} = \frac{\text{Value of the coin}}{\text{Price per ounce of gold}} \]
Given that the value of the coin is $3200.00 and the price of gold is $800.00/oz, the calculation would be:
\[ \text{Weight} = \frac{3200}{800} = 4 \text{ oz.} \]
So, the coin weighs 4 oz.
