Just need help solving these word problems
Let C= no of children
A= no of adults
Then:
A+C=400 this is the statement that the sum of the people (adults and children) was 400
3*A+2*C=900 this says that each adult paid $3 and each child paid $2 for a ticket and the total amount
(the sum) spent was $900
Solving gives A=100 C=300/
