Answer:
The cost of printing posters 2 to 100 is $9.
Step-by-step explanation:
The marginal cost of printing a poster when x posters have been printed is
We need to find the cost function.
Seprate the variables.
Integrate both sides.
where, C is an arbitrary constant.
We need to find the value of c(100)-c(1).
Substitute x=100 in the above function.
Substitute x=1 in the above function.
Therefore, the cost of printing posters 2 to 100 is $9.
