Ad libitum [116K]

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 $C(q)=1300+2q^2$ dollars.

$C(12)=1300+2(12)^2=1588\\\\ C(11)=1300+2(11)^2=1542$

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.

Gwar [14]

Answer:

$Each = 3\frac{1}{3}$

Step-by-step explanation:

Given

$Balls = 4\ pack$

$Gums = 5\ each$

First we need to determine the number of gums

$Total = 4 * 5$

$Total = 20$

Divide 20 among 6 friends

$Each = \frac{20}{6}$

$Each = 3\frac{1}{3}$

Hence;

Each friend gets $3\frac{1}{3}\ gum$
