| Question | Answer |
|---|---|
| TR | Total Revenue = price × quantity |
| TC | Total Cost = FC + VC |
| FC | Fixed Cost: cost that stays the same as output changes in the short run |
| VC | Variable Cost: cost that changes with output |
| MC | Marginal Cost = ΔTC ÷ ΔQ |
| AFC | Average Fixed Cost = FC ÷ Q |
| AVC | Average Variable Cost = VC ÷ Q |
| ATC | Average Total Cost = TC ÷ Q |
| MPL | Marginal Product of Labor = ΔQ ÷ ΔL |
| SRATC | Short-Run Average Total Cost: average total cost when at least one input is fixed |
| LRATC | Long-Run Average Total Cost: lowest average total cost at each quantity when all inputs can change |
| Q | Quantity of output produced |
| L | Labor, measured as the number of workers in the slides |
| Δ | Change in = new value − old value |
| ΔQ | Change in quantity |
| ΔL | Change in labor |
| ΔTC | Change in total cost |
| ΔVC | Change in variable cost |
| A | average |
| M | marginal |
| F | fixed |
| V | variable |
| T | total |
