Select the graph that matches the numbered manufacturing cost data. Indicate by letter which of the graphs best fits each of the situations or items described. (Click to view the graphs.) The vertical axes of the graphs represent total dollars of cost, and the horizontal axes represent production output during a calendar year. In each case, the zero point of dollars and production is at the intersection of the two axes. The graphs may be used more than once. 6. Rent on a manufacturing plant donated by the city, where the agreement calls for a fixed fee payment unless 200,000 labour-hours are worked, in which case no rent need be paid. 7. Salaries of repair personnel, where one person is needed for every 1,000 machine-hours or less (that is, 0 to 1,000 hours requires one person, 1,001 to 2,000 hours requires two people, etc.). 8. Cost of direct materials used (assume no quantity discounts). 9. Rent on a manufacturing plant donated by the county, where the agreement calls for rent of $100,000 reduced by $1 for each direct manufacturing labour-hour worked in excess of 200,000 hours, but a minimu rental fee of $20,000 must be paid.
