nalin [4]

Answer:

$160

Step-by-step explanation:

El monto total a pagar es de $350

$\dfrac{1}{7}$ es pagado por mamá

$\dfrac{2}{5}$ es pagado por el hermano mayor

La porción pagada por papá es

$1-(\dfrac{1}{7}+\dfrac{2}{5})=1-(\dfrac{5+14}{35})\\ =1-\dfrac{19}{35}\\ =\dfrac{35-19}{35}\\ =\dfrac{16}{35}$

Esta cantidad pagada por papá es

$350\times\dfrac{16}{35}\\ =10\times 16\\ =\$160$

Esta cantidad pagada por papá es $160.
