Alex Ar [27]

Answer:

Nancy gastó 8,58 dólares.

Step-by-step explanation:

Para calcular cuánto dinero gastó Nancy, debemos hallar la relación entre Nancy y María, tal como sigue:

M = 3N    (1)

En donde M es por María y N por Nancy

En la relación de la equación (1) tenemos que el dinero que gastó María es 3 veces lo que gastó Nancy, tal como dice el enunciado.

Entonces, podemos hallar ahora cuánto gastó Nancy:

N = \frac{M}{3} = \frac{25,75}{3} = 8,58

Por lo tanto, Nancy gastó 8,58 dólares.  

Espero que te sea de utilidad!
