Suppose a company is producing a new logic board for computers.

The annual fixed cost for the board is $345,000 and the variable cost is $125 per board.

Suppose the logic board is sells for $489.

To find an inequality that gives the number of logic boards that will give a profit for the product:

Suppose there are number of logic boards in a unit.

If the total unit is purchased at one time then the cost is $345,000.
