Suppose the total cost (in rand) of manufacturing grass
brooms is
TC 10u²-4u +14
=
where u is the number of grass brooms manufactured.
What is the marginal cost if 100 brooms are
manufactured?
a.
99 614
b.
сто
5
C.
1996
d.
996



Answer :

Answer:

C

Step-by-step explanation:

Marginal cost is the derivative of total cost with respect to the number of units produced.

Given TC = 10u² - 4u + 14, the marginal cost is the derivative of TC with respect to u:

MC = d(TC)/du = d(10u² - 4u + 14)/du = 20u - 4

Substitute u = 100 into the equation to find the marginal cost when 100 brooms are manufactured:

MC = 20(100) - 4 = 1996 Rand
