A manufacturing company has a total cost functions

c =5Q+ 180Q +12500
This gives the total cost of producing Q untis
a) find a formula for the units cost U in terms of Q where U = C/Q
b)find the value Q that minimises the unit cost find this minimum unit cost.

What have you done so far?

Assuming you meant C=5Q^2+ 180Q +12500
(a) U=C/Q = 5Q+ 180 +12500/Q
(b) dU/dQ = 5 - 12500/Q
minimum is U(50) = 680
