Answer:
The number of children is 7 and adult is 4
Explanation:
I. Mrs Adams paid total 48 euro, for 4 adults and x children
When adult ticket cost 5 euro and children cost 4 euro
So Total price = Adult price + Children price
48 = 5(4) + 4(x)
48 = 20 + 4x
48 - 20 = 4x
28 = 4x
x = 28 ÷ 4
x = 7
Thats makes Mrs Adams bought ticket for 4 adults and 7 children.
4 adult costs 20 and 7 children costs 28
Hope that help :)
