Answer:
El promedio de dinero de las personas es de $35 cada uno.
Step-by-step explanation:
Dado que el promedio del dinero de 5 personas es de $20 cada uno, para determinar, si ingresan 3 personas con promedio de $60 cada uno, cuál es promedio del dinero de las personas
, se debe realizar el siguiente cálculo:
((5 x 20) + (3 x 60)) / 8 = X
(100 + 180) / 8 = X
280 / 8 = X
35 = X
Por lo tanto, el promedio de dinero de las personas es de $35 cada uno.

Step-by-step explanation:
For 1 house, the charge just to go to a house is $12.
In each house you made $57.

$45/($9/hr) = 5 hours
You shoveled 5 hours in each house.
3 * 5 hours = 15 hours
Answer: 15 hours
