Para pagar la entrada al circo y comprar palomitas: Daniela y María van a cooperar con $65.50 cada una y Francisco y Javier con $69.50 cada uno. ¿Cuánto dinero van a reunir?

Reunirán $270.

Explanation:

Para pagar la entrada al circo y comprar palomitas Daniela y María van a cooperar con $65.50 cada una. Entonces para calcular el dinero que van a reunir entre ambas debes sumar lo que aporta cada una:

$65.50 + $65.50= $131

Por otro lado, Francisco y Javier van a cooperar con $69.50 cada uno. De igual manera, para calcular el dinero que van a reunir entre ambos debes sumar lo que aporta cada uno:

$69.50 + $69.50= $139

Para conocer el dinero total recaudado, debes sumar lo que aportan tanto ellas como ellos. Esto es:

$131 + $139= $270

Reunirán $270.
