I'm helping my daughter with a math problem......here's the question:
Expenses = 5 + 12x
Income = 25 + 14x
Therefore, Profit = (25 +14x) - (5 +12x) right?
Now the question is.....How many sweatshirts "x" must be sold to "break even"?
The way I worked the problem was to make Profit "P" equal to zero. But when I do this, I come out with x = -10 shirts. I know that can't be right. What are we doing wrong? Please explain in detail so we can understand where we went wrong. Thanks!
