Answer:
First, write the two equations letting c=children and a=adults :c+a=2200
1.50(c)+4.00(a)=5050
Explanation:
Now, use substitution ...c=2200−a
1.50(2200−a)+4.00(a)=5050
Simplify ...2.5a=1750
a=700
Using the first equation ...c
=2200−a=2200−700=1500
In summary, there were 700 adults and 1500 children .
