Dmitry_Shevchenko [17]

Answer:

La familia de Trevor gastó 86.4 dólares al bañarse en todo el mes.

Step-by-step explanation:

El costo del agua viene dado por:

$C = \$0.20/L$ (1)

Y cada persona de la familia de Trevor gasto en promedio 72 litros de agua. Si la familia tiene 6 integrantes (incluido Trevor) entonces:

$A = 72 L*6 = 432 L$ (2)

Entonces, toda la familia usó 432 litros de agua en promedio en todo el mes.

Para saber el dinero total gastado por la familia debemos multiplicar la ecuación (1) y la ecuacion (2):

$C = \$0.20/L*432 L = \$86.4$

Por lo tanto, la familia de Trevor gastó 86.4 dólares al bañarse en todo el mes.

Espero que te sea de utilidad!
