Answer:
60 child tickets were sold
Explanation:
Let no of children tickets sold that day be c and adult tickets be a
Then since total number of tickets sold is 148, we have
c+a = 148 ... i
Also given that admission fee is 6.00 for children and 9.70 for adults
So for c children tickets sold value= 6c and for adults it is 9.7a
total revenue = 6c+9.7a=1213.60 ... ii
We got two equations in two variables c and a
Let us solve this
a =148-c. substitute this in ii
6c+9.7(148-c) = 1213.60
Simplify the above to have
222 = 3.7c
Or c = 60
No of child tickets sold = 60
