can you solve this one?

At a certain factory, the marginal cost is 3(q - 4)2 dollars per unit when the level of production is q units. By how much will the total manufacturing cost increase if the level of production is raised from 6 units to 10 units?

Make sure you posted the correct expression for the marginal cost.

Please show us what you have tried and exactly where you are stuck.

Please share your work/thoughts about this assignment.

If you cannot even start, review the definitions of terms such as marginal cost.

I am going to guess that you mean 3(q- 4)^2- that is, q- 2 is squared. Do you understand what "marginal cost" means? It is the change in cost when the level of production is increased by 1 unit. So going from 6 to 7 units, cost will increase by 3(6- 4)^2= 3(4)= 12. Going from 7 to 8 units, cost will increase by 3(7- 4)^2= 3(9)= 27. How much will costs increase going from 8 to 9 units? How much will costs increase going from 9 to 10 units? How much does that total?
 
thanks for your comment

when it's 6 ---12
7---------------27
8---------------48
9---------------75

and then?

Your table is not correct.
As HallsofIvy stated:
Increase from 6 to 7 is 12
Increase from 7 to 8 is 27
....

So how much will the total manufacturing cost increase if the level of production is raised from 6 units to 10 units
