Course: Mathematical Fundamentals
Topic: Application of Derivatives in Economic Problems
A manufacturer determines that "t" employees will produce a total of "q(t)" units per day, where:

<See attached image 1>

If demand equation for product (price) is given by:

<See attached image 2>

(a) Determine RATE OF CHANGE of income "I" with respect to "t" workers.
b) What is RATE OF CHANGE of income when there are 12 workers?

(b)d
=
4500
q+10
Transcribed Image Text:(b)d = 4500 q+10
q(t)
=
5t + 20
√3t² + 100
Transcribed Image Text:q(t) = 5t + 20 √3t² + 100

Follow-up Question

First. Income function is Income = p(q) * q. I don't see that part in development.
Second. When there is variable "q" as (q+10)^2 on denominator , it can be replaced by q(t) from statement, since it asks for rate of change of I over t.

So I see that something is missing in development, to then replace t = 12 workers. And I think is "dI/dt", no "dp/dt", where dI is Income partial derivate
