nations (qL, 9c) to generate 12 units a day are economically sound.
16. The production q (in units) of a certain good in terms of the amount q of labour invested and
the amount qc of capital invested is given by the production function q = 5-qL2/3-qc1/3. At this
moment, 512 units of labour and 1000 units of capital are invested daily. This means that at this
moment, 3 200 units are produced daily. The graph below gives the contour line of level 3 200 of the
production function.

Figure 8: Contour line of level 3 200 of the production function q.
(a) Give an implicit and explicit equation of this contour line.
Assume for this and later parts that a unit of labour costs 1.89 units of money and that a unit of
capital costs 1.25 units of money. Moreover, there is a fixed cost of 14.3 units of money a day.
(b) Give the equation of the cost function c(qL, 9c).
(c) Graph, in Figure 8 above, a line that allows you to decide that there exists another combination
(9L.qc) to generate 3 200 units a day with exactly the same cost as the combination (q1,qc) =
(512, 1000).
(d) Explain how you can approximately read this second combination from the graph above.
(e) Calculate this second combination exactly. Make use of your graphing calculator.
(f) Explain how you can graphically find the combinations to produce 3 200 units a day in a cheaper
way than by investing (qL, 9c) = (512, 1000).
(g) Describe the method to find the minimal budget to reach the daily production level q = 3200
geometrically.
(h) Calculate the minimal cost to realize production level q = 3200 and the number of units of
capital and labour that have to be invested.
