Vitek1552 [10]

Answer:

Costo fijo= $104.5

Costo unitario=  $0.5 por minuto

Step-by-step explanation:

Mes pasado:

$239 por 269 minutos

Mes corriente:

$175 por 141 minutos

<u>Primero debemos calcular el cost por minuto de llamada:</u>

Costo unitario= (costo total más alto - costo total más bajo) / (cantidad de minutos más alto - cantidad de minutos más bajo)

Costo unitario= (239 - 175) / (269 - 141)

Costo unitario=  $0.5 por minuto

<u>Ahora, el costo fijo:</u>

Costo fijo= costo total más alto - (costo unitario*cantidad de minutos más alto)

Costo fijo= 239 - (0.5*269)

Costo fijo= $104.5

Costo fijo= costo total más bajo - (costo unitario*cantidad de minutos más bajo)

Costo fijo= 175 - (0.5*141)

Costo fijo= $104.5
