Let c be children and a adults.
3.5c + 7a = 1771 (the total revenue is equal to the amounts made off of people)
c + a = 331 (total number of people)
The second formula becomes a = 331 - c. This can be substituted into the first formula.
3.5c + 7(331 - c) = 1771 = 7*331 - 3.5c = 1771. 7*331 = 2317, so 3.5c = 2317 - 1771 = 546.
546/3.5 = 156 = c (number of children).
c + a = 156 + a = 331 => a = 331 - 156 = 175 (number of adults).
There are 156 children and 175 adults

#420
because 70x4=420 within 300 and 500 and is greater than 400 which is a multiple of 100
Answer:
Hay un máximo de tres ceros en el producto de un número distinto de cero cero menor que 10 y 500
Para poder ver esto, la forma más fácil para resolver este problema es multiplicar todos los números entre 1 y 9 por 500, es decir:
01*500 = 500
2*500 = 1.000
3*500 = 1.500
4*500 = 2.000
5*500 = 2.500
6*500 = 3.000
7*500 = 3.500
8*500 = 4.000
9*500 = 4.500
Como vemos, si multiplicamos a 500 por cualquier número par, entonces obtenemos un número con tres ceros, mientras que si este es impar solamente obtenemos dos ceros
