Question

if gold is currently trading at 800.00 /oz and you inherit a gold coin worth 3200.00 how much does the coin weigh

Answer 1

Answer = 4 oz


Step-by-step 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


`(p1)/(w1)` =
`(p2)/(w2)`

⇒
`(800.00)/(1)` =
`(3200.00)/(w2)`

⇒ w₂ =
`(3200.00)/(800.00)`

⇒ w₂ = 4 oz

The coin weighs 4 oz
