11.25x - 2900 > 0
11.25x > 2900
x > 2900/11.25
x > 258.22
Therefore, 259 or more compact discs should be sold to yield a positive profit.
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= boxed 13x (Simplify your answer.)
(c) Profit equals revenue minus cost. Write a formula that calculates the profit P from selling x compact discs.
P = 11.25x - 2900 (Simplify your answer.)
(d) How many compact discs need to be sold to yield a positive profit?
