Answer:
26 child tickets
Explanation:
Let's assume the number of child tickets sold is "x".
According to the given information, the number of adult tickets sold is twice the number of child tickets sold, so the number of adult tickets sold would be "2x".
The total sales from child tickets can be calculated by multiplying the number of child tickets by the child admission price:
Total sales from child tickets = $6.30 * x
Similarly, the total sales from adult tickets can be calculated by multiplying the number of adult tickets by the adult admission price:
Total sales from adult tickets = $9.80 * (2x)
The total sales from both child and adult tickets is given as $673.40:
Total sales from child tickets + Total sales from adult tickets = $673.40
Substituting the expressions for the total sales:
$6.30 * x + $9.80 * (2x) = $673.40
Simplifying the equation:
6.30x + 9.80(2x) = 673.40
6.30x + 19.60x = 673.40
25.90x = 673.40
Dividing both sides by 25.90:
x = 26
Therefore, 26 child tickets were sold on Monday.
