(a) Graph the following curve:

Y = 120x-0.322 General form: y = ax-b For values of x = 1,2.4.25,1 00, 200

(b) Given that:

y = average no. of direct labour hr per unit a = no. of direct labour hr for first unit x = the cumulative no. of units produced Comment on the graph, and suggest circumstances in which the use of such a graph would assist in management accounting (assume for example, that an order for additional units has been received).
