Answer = 4 oz
EXPLANATION
Let weight = w
Let price = p
We are told that gold is currently trading at 800.00 /oz
⇒ 1 oz of gold is worth 800.00
w₁ = 1 oz
p₁ = 800.00
The gold coin inherited is worth 3200.00
The weight of gold coin inherited = ?
w₂ = ?
p₂ = 3200.00
[tex] \frac{p1}{w1} [/tex] = [tex] \frac{p2}{w2} [/tex]
⇒ [tex] \frac{800.00}{1} [/tex] = [tex] \frac{3200.00}{w2} [/tex]
⇒ w₂ = [tex] \frac{3200.00}{800.00} [/tex]
⇒ w₂ = 4 oz
The coin weighs 4 oz
