An analysis of a particular cost incurred in a factory revealed that the cost averages $0.40 per machine-hour at an activity level of 20,000 machine hours and increases to an average of $0.50 per machine-hour at an activity level of 16,000 machine hours. Assuming that this activity is within the relevant range, what is the total expected cost if the activity level is 17,300 machine hours?
