Respuesta:
71.41 kilogramos
Explicación paso a paso:
En este caso lo que debemos hacer para calcular el peso de los artículos vendidos, es sumar el peso individual de cada artículo, por lo tanto:
Peso total = peso del arroz + peso de la papa + peso del frijol
Ya que tienen la misma unidad de medida, no hay ningún problema para sumar, entonces reemplazamos:
Peso total = 20 + 12.25 + 39.16
Peso total = 71.41
Lo que quiere decir que el peso de los artículos vendidos es de 71.41 kilogramos
