Question 846746: Frank makes and sells small picture frames. His revenue from sales can be represented as R=$13.60x for x frames sold. The cost of making the frames can be represented as C=$5.80x +$120 for x frames made. What is the minimum number of frames Frank must sell in order for his revenue to be greater than his costs.

If profit = , then



Make the profit zero, which means



You can't have a fraction of a frame,

profit when he sells 16 frames
