There were 225 tickets sold for the ballgame. Children's' tickets were $1 and adults' tickets were $2. If
the total amount of tickets sold was $400, how many of each type were sold?

Respuesta :

Answer: 175 adult and 50 children

Step-by-step explanation:

1x+2y=400

x+y=225

subtract x

y=225-x

substitute for y in first set

1x+2(225-x)=400

1x+450-2x=400

450-x=400

-x=-50

x=50

substitute for second set

50+y=225

y=175
