He has a contract to sell $5$5 tons of cocoa next month at $\$2.30$$2.30 per pound, and has found a second buyer who has agreed to buy his cocoa immediately at $\$9.20$$9.20 per pound.


Assuming he has already been paid for next month's contract, solve for $n$n, the number of tons of cocoa he needs to sell to the second buyer to break even immediately.
