Answer 1

Answer: There are 152 adults and 87 children.

Explanation:

Let x= Number of adults

y= Number of children

As per given, we have

x+y = 239 (i)

15x+5.50y= 2758.50 (ii)

Multiply 5.50 on both sides of (i) , we get

5.50x+5.50y=1314.5 (iii)

Subtract (iii) from (ii), we get

9.5x = 1444

⇒ x = 152

Put value of x in (i) , we get

152+y=239

⇒ y= 239-152

⇒ y= 87

Hence, there are 152 adults and 87 children.
