Primero, calculamos el precio de venta con la información facilitada en relación al markup o margen:
60 + 0,25*P =P; P = 80.

A continuación, aplicamos el descuento del 20% y le restamos los 60 euros del coste de adquisición:
80 - 80 * 0,20 = 80 - 16 = 64.

Gross profit = 64 - 60 = 4.

Respuesta: C.
