A truck is shipping jugs of drinking water and cases of paper towels. A jug of drinking water weighs 40 pounds and a case of paper towels weighs 16 pounds. The truck can carry 2,000 pounds of cargo altogether. (jug of water is w and case of paper towels is t) The question is: Write an equation relating the number of jug of water and the number of cases of paper towels the truck can carry.

Thanks! :)​
