Answer:
60 tickets
Step-by-step explanation:
At a movie theater, children admission = $6.30
And adult admission = $9.70
On Monday, 132 tickets were sold for a total of $1076.40
Let the number of child tickets be x ,
and the number of adult tickets be y.
This forms a simultaneous equation:
x + y = 132 ... (i)
$6.30x + $9.70 = $1076.40 ... (ii)
Multiplying (i) by 6.3 and (ii) by 1 we get;
6.3x + 6.3y = 831.6 ... (i)
6.3x + 9.7y = 1076.4 ... (ii)
Subtracting (ii) - (i) we get;
3.4y = 244.8
y = 72
The number of child tickets were; 132 - 72 = 60
