Answer: Marginal cost = $46
The cost of production increases by about $46 when one additional unit is produced.
Step-by-step explanation:
Given : The cost to produce q items is [tex]C(q)=1300+2q^2[/tex] dollars.
[tex]C(12)=1300+2(12)^2=1588\\\\ C(11)=1300+2(11)^2=1542[/tex]
The marginal cost of producing the 12th item= C(12)-C(11)
=1588-1542=46
Interpretation : It means , the cost of production increases by about $46 when one additional unit is produced.
