Suppose that you can sell as much of a product (in integer units) as you like at $68 per unit. Your marginal cost (MC) for producing the qth unit is given by:

MC=10q

This means that each unit costs more to produce than the previous one (e.g., the first unit costs 10*1, the second unit (by itself) costs 10*2, etc.).

1.)If fixed costs are $60, what is the optimal integer output level?

2.) If fixed costs are $60, what is the profit at the optimal integer output level?

3. If fixed costs are $85, what is the optimal integer output level?

4. If fixed costs are $85, what is the profit at the optimal integer output level?
