Answer:
the production function always follows this pattern: Q = K + L
Q = quantity of output
K = quantity of capital
L = quantity of labor
in this case, since you need 3 cooks and 5 units of food to prepare 5 meals, the production function is:
M = 3C + 5F
where;
M = five course meal
C = cooks
F = units of food
the cost function always follows this pattern: C = FC + VC
C = total production cost
FC = fixed costs
VC = variable costs
since the price of a cook is 100 per cook and the price of food is 50 per food unit, the production cost function is:
M = 100L + 50F
where:
C = production cost of a course meal
L = number of cooks required
F = units of food required
C = ($100 x 3) + ($50 x 5) = $550
in this case we were only given variable costs, so this cost function does not include any fixed costs.
