| A | B |
| R(x) | Revenue (money brought in) |
| C(x) | Cost (money spent) |
| P(x) or Pi(x) | Profit (money left over) |
| When R(x) = C(x), the profit is | 0 |
| For R(x) = 24x, how much is each unit seeling for? | 24 |
| For C(x) = 20x + 100, how much is each unit selling for? | 20 |
| For C(x) = 20x + 100, what is the fixed cost? | 100 |
| y=24x is what type of function? | Linear |
| Is 24x a fixed or variable cost? | Variable only |
| Is 20x + 100 a fixed or variable cost? | Both |
