Answer:
The number of adult ticket sold is [tex]12[/tex]
The number of child ticket sold is [tex]38[/tex]
Step-by-step explanation:
Given cost of adult tickets are $[tex]8[/tex], and cost of child tickets are $[tex]4[/tex]
Let the number of adult ticket sold is [tex]x[/tex]
Also, the number of child ticket sold is [tex]y[/tex]
We can write two equation from given information.
[tex]x+y=50\ Equation\ (1)\\8x+4y=248\ Equation(2)[/tex]
Now, plug [tex]x=50-y[/tex] in [tex]Equation(2)[/tex] we get,
[tex]8(50-y)+4y=248\\400-8y+4y=248\\-4y+400=248\\-4y=248-400\\-4y=-152\\y=\frac{-152}{-4}\\y=38[/tex]
Now, from [tex]Equation(1)[/tex]
[tex]x+y=50\\x+38=50\\x=50-38\\x=12[/tex]
So, The number of adult ticket sold is [tex]12[/tex]. And the number of child ticket sold is [tex]38[/tex]
