just need last value!

Futures Profits (LO3, CFA4) The contract size for platinum futures is 50 troy ounces. Suppose you need 600 troy ounces of platinum and the current futures price is $1,120 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 $1,145 a troy ounce when the futures contract expires? What if the price is $1,065 at expiration? (A negative value should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to the nearest whole number.)
