The bagel store orders cream cheese from 3 suppliers, Cheesy Cream Corp. (CCC), Super Smooth & Sons (SSS), and Bagel's Best Friend Co. (BBF). 1 month, total order of cheese came to 100 tons (they perform the booming trade). Costs were $80, $50 and $65 per ton from three suppliers respectively, with total cost amounting to $6,620. Provided that store ordered same amount from CCC and BBF, find out how many tons of cream cheese were ordered from each supplier?
