Hi a few questions i want to check my answers for here,
3. Write down an expression, evaluate the constant of proportionality, and answer the question.
[Remember to work in SI units. Simplify answers to 1 d.p. only.]
(a) The annual cost (C) of running a business is partly constant and partly proportional to the number of employees.
If there are 20 employees, the annual cost is $400000.
If there are 25 employees, the annual cost is $470000.
Find the annual cost if there are 18 employees
What is meant by partly constant? how would this be written.
C = kN? or C = kN + c?
