Grado | Precio por pielineal. (US) | No. De Yardas | Conversión a pies | Costo total |
A | $5.00 | 100 | 300 | 1500 |
B | $3.50 | 150 | 450 | 1575 |
C | $2.50 | 75 | 225 | 562.5 |
D | $2.00 | 200 |600 | 1200 |

Si 1 yarda = 3 pies
Costo promedio= ∑costo total ÷∑No. De yardas
=4837.5÷1575= 3.0714

Mayor consistencia:
1° maquina = 11.9
Promedio = ∑pulgadas ÷8=
=95.9÷8= 11.9875

2°maquina=11.9
Promedio = ∑pulgadas÷7
=83.9÷7= 9.32
