A firm's revenue function is given by R (x)=12x-0.01x2 and its cost function is given by C (a) = 7x. From the cost function, the fixed cost is $ [Select] and the variable cost is [Select] We know the firm's fixed cost is $ [Select] when it produces the 10th unit. When the firm produces and sells 10 units, its total profit is $ [Select] However, 10 units may not be the firm's profit-maximizing output. Perhaps, the 10 units will not even help the firm break even. Based on the given cost and revenue functions, the firm maximizes its profit when it produces [Select] units. The firm breaks even when it produces [Select] units. We can deduce some other cool information from the firm's given cost function. For instance, based on the cost function we know the average cost is [Select] [Select] marginal cost is and average fixed cost is [Select] The marginal revenue when the firm sells the 10th unit is [Select] number). Based on this, we know the firm's revenue must be [Select] sells the 10th unit. (to the nearest whole at the point where it
