Profit is the difference between the selling price and the cost price. Andy will make $250,000 in the deal.
Profit or loss is the difference between the selling price and the cost price. If the difference is positive then it is profit, if the difference is negative it is a loss.
We know that Andy sold 5,000 troy ounces of gold at $1,000 per ounce in 36 months. But now as he has already sold the gold troy he needs to buy back those 5,000 troy to fulfill the sold gold troy. If he tries to buy back those troy right now at a price of $950. Then, the profit he will make,
[tex]\rm Profit=(Sold\ price - Cost\ price)\times Number\ of\ troy[/tex]
[tex]\rm Profit = (1000-950) \times 5,000\\\\Profit = \$ 250,000[/tex]
Hence, Andy will make $250,000 in the deal.
