The contract size for platinum futures is $50$ troy ounces. Suppose you need $700$ troy ounces of platinum and the current futures price

is $$780$ per ounce. How many contracts do you need to purchase? How much will you pay for your platinum? What is your dollar profit

if platinum sells for $$830$ a troy ounce when the futures contract expires? What if the price is $$730$ at expiration?

Note: A negative value should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to the

nearest whole number.
