| Month | Hours | Cost | |
| March | $ 4,440 | $ 50,950 | |
| April | $ 4,431 | $ 50,877 | |
| May | $ 4,412 | $ 50,696 | |
| June | $ 4,460 | $ 51,113 | |
| July | $ 4,414 | $ 50,711 | |
| August | $ 4,433 | $ 50,900 | |
| September | $ 4,443 | $ 50,976 | |
| October | $ 4,415 | $ 50,730 | |
| November | $ 4,391 | $ 50,530 | |
| High | $ 4,460 | $ 51,113 | |
| Low | $ 4,391 | $ 50,530 | |
| Variable cost | $ 8.4493 | ||
| = (51113-50530)/(4460-4391) | |||
| Fixed cost | $ 13,429 | ||
| = 51113-4460 × 8.45 | |||
| Equation= | Cost = 8.4493 × Hours + 13429.23 | ||
| Cost at 4000 hours: | $ 47,226.33 | ||
| [ 4000 * 8.4493 + 13429.23 |
