A 1 de Mayo tendremos 4X brooms
A 31 de Diciembre quedarán 0 debido a 4X - \frac{8X}{2}[/m]
A 2 de Mayo ya se ha vendido el primer lote de \frac{X}{2}[/m] brooms por lo que durante dicho mes almacenaremos \frac{7X}{2}[/m]
Así en adelante todos los meses \frac{6X}{2}[/m], \frac{5X}{2}[/m], \frac{4X}{2}[/m], ... hasta 0 en Diciembre.
Sabiendo que el coste es 1 para cada mes, el coste total es la suma de todos los brooms que almacenamos que es 14X
