Answer:
40 divided by 10
Step-by-step explanation:
Connect the arrows with a straight line
(x + 7)(x + 4)
(x² + 4x + 7x + 28)
x² + 11x + 28
Let children be x
Adult be y
5.10x+9.40y=1184.20 ... 1
x+y=158 ... 2
From 1// 510x+940y=118420 ... 3
From 2// y=158-x ... 4
Sub 4 into 3
510x+940(158-x)= 118420
510x+148520-940x=118420
-430x= -30100
x=70
As we know that children are x, 70 children tickets were sold.
