Solution:
0.2462

A)
Ventas. 14
Costo de bienes vendidos. (8)
Depreciación. (2)
Intereses (1)
Beneficio neto antes de impuestos=3 millones
Impuesto. 0.35×3 = (1.05)
Ingreso neto= 1.95
Flujo de efectivo= ingreso neto+ depreciación
Flujo de efectivo=1.95+2=3.95
B)
Ingreso neto=1.95-1=0.95
Flujo de efectivo=3.95+1=4.95
