At the movie theater, childs admission is $6.10. Adult admission is $9.40. On Tuesday four times as many adult tickets as child

Harlamova29_29 [7]

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

$6.10x+9.40y=1,179.90$ ----> equation A

$y=4x$ ----> equation B

Solve the system by substitution

Substitute equation B in equation A

$6.10x+9.40(4x)=1,179.90$

solve for x

$6.10x+37.6x=1,179.90$

$43.7x=1,179.90$

$x=27$

therefore

The number of children's tickets sold was 27
