A greeting card company can sell cards for $2.75 each, so the revenue can be calculated using the formula 2.75 Rx . The company’
LuckyWell [14K]
Given that the revenue equation is R(x)=2.75x and the cost equation is C(x)=0.35x+12,000



Part A:

At break-even the cost is equal to the revenue.

Thus, the algebraic equation needed to determine when the company will break even is given by

R(x)=C(x) \\  \\ \Rightarrow2.75x=0.35x+12,000



Part B:

The solution to part A is given as follows:

2.4x=12,000 \\ \\ \Rightarrow x=5,000



Part C:

<span>The algebraic inequality needed to indicate that the revenue is greater than the cost is given by

R(x)\ \textgreater \ C(x) \\ \\ \Rightarrow2.75x\ \textgreater \ 0.35x+12,000



Part D:

</span>The solution to part C is given as follows:

2.4x>12,000 \\ \\ \Rightarrow x>5,000



Part E:

The answer in part D tells us that the the company will make a profit when the produce more than 5000 cards.
