Solve the problem.
-A chess master creates instructional videos about various opening strategies. She sells the videos in 3 -hr packages for

\$ 35

each. Her one-time initial cost to produce each 3 -hr video package is

\$ 4,600

(this includes labor and the cost of computer supplies). The cost to package and ship each DVD is \$2.95.
a. Write a linear cost function that represents the cost

C ( x )

to produce, package, and ship

x 3 - \mathrm { hr }

video packages.
b. Write a linear revenue function to represent the revenue

R ( x )

for selling

x 3

-hr video packages.
c. Evaluate

( R - C ) ( x )

and interpret its meaning in the context of this problem.
A) a.

C ( x ) = 8.85 x + 4,600

;
b.

R ( x ) = 35 x

( R - C ) ( x ) = 26.15 x - 4,600

represents
the profit for selling

x

DVDs.

B) a.

C ( x ) = 35 x

R ( x ) = 2.95 x + 4,600

;
c.

( R - C ) ( x ) = 32.05 x - 4,600

represents
the profit for selling

x

DVDs.

C) a.

C ( x ) = 2.95 x + 4,600

;
b.

R ( x ) = 35 x

( R - C ) ( x ) = 32.05 x - 4,600

represents
the profit for selling

x

DVDs.

D) a.

C ( x ) = 8.85 x + 4,600

;
b.

R ( x ) = 35 x

( R - C ) ( x ) = 4,600 - 26.15 x

represents
the profit for selling

x

DVDs.
