Answer:
138 tickets were sold to adults and 62 to children.
Explanation: Let x be the number of tickets sold to adults. If there are 200 tickets sold in total, the number of tickers sold to children is 200-x. To solve this, we setup the equation and it should look like this:
8x+5(200-x)= 1414
8x+1000-5x=1414
3x=414
x=138
138 tickets were sold to adults and 62 to children.
