When you want to say " the food, the thing that people eat in general", can you say the produce? For instance, The consequences of the catastrophe triggered the decrease in produce exports into Japan. (In the sentence I wanted to say "only food", but does this want have the same meanings, as the products -- i.e. things in general?

Because it is more efficient to produce larger numbers of items, the cost of producing Dysan computer disks is inversely proportional to the number produced. If 4000 can be produced at a cost of $1.20 each. Find the cost per disk when 6000 iare produced. How can I solve this problem?
