The cost to produce one compact disc is $1.75 plus a one-time fixed cost of $2900. The revenue received from selling one compact disc is $13.

(a) Write a formula that gives the cost C of producing x compact discs. Be sure to include the fixed cost.
C = 1.75x + 2900 (Simplify your answer.)

(b) Write a formula that gives the revenue R from selling x compact discs.
R = __ (Simplify your answer.)

R = 13x

(b) The formula that gives the revenue R from selling x compact discs is:

R = 13x

(b) To find the formula for revenue, we need to consider that the revenue received from selling one compact disc is $13.

Since the revenue is the amount earned per compact disc, we can simply multiply the number of compact discs sold (x) by the revenue received per compact disc ($13).

So, the formula for revenue (R) from selling x compact discs is:

R = 13x
