%path = "maths/linear system/costs" %kind = kinda["problems"] %level = 10 The production costs K of a product are linear. For {{g.A[0][1]}} units the costs are €{{g.b[0]}} and for {{g.A[1][1]}} units they are €{{g.b[1]}}. Calculate the variable unit costs \(\bar{K_v}\) and the overheads (fixed costs) \(K_f\). %chq(chames=[r'\(K_f\) = €',r'\(\bar{K_v}\) = €'])
