Answer:

The number of children's tickets sold was 27

Step-by-step explanation:

Let

x ----> the number of children's tickets sold

y ----> the number of adult's tickets sold

we know that

[tex]6.10x+9.40y=1,179.90[/tex] ----> equation A

[tex]y=4x[/tex] ----> equation B

Solve the system by substitution

Substitute equation B in equation A

[tex]6.10x+9.40(4x)=1,179.90[/tex]

solve for x

[tex]6.10x+37.6x=1,179.90[/tex]

[tex]43.7x=1,179.90[/tex]

[tex]x=27[/tex]

therefore

The number of children's tickets sold was 27
