Suppose that you can sell as much of a product (in integer units) as you like at $43 per unit. Your marginal cost (MC) for producing the qth unit is given by:

MC=8q

This means that each unit costs more to produce than the previous one (e.g., the first unit costs 8*1, the second unit (by itself) costs 8*2, etc.).

If fixed costs are $350,what is the optimal integer output level?

Please specify your answer as an integer.
