Write an expression for the problem, then evaluate.
Tickets for children in a carnival cost 150. A teacher of a class of 48 pupils gets for the whole class but only 43 pupils buy. Is it right for the teacher to say that she has 6,350 for the tickets of the children? Why
Gets what?
The 48 is just noise. The cost (c) of the tickets for p pupils is
c = 150p
150*43 = 6,450
So, the figure of 6,350 is incorrect.
Whether or not it is wrong for the teacher to say otherwise is a moral question ...

To solve this problem, we can start by writing an expression for the total cost of the tickets that the teacher claims to have collected.
Let's calculate the expression:
Total cost of the tickets = Cost per ticket * Number of pupils who bought tickets
Given:
Cost per ticket = $150
Number of pupils who bought tickets = 43
Total cost of the tickets = $150 * 43 = $6,450
Now we can compare the calculated total cost of the tickets to what the teacher claims to have collected ($6,350).
Since the calculated total cost of the tickets is $6,450, which is different from the teacher's claimed value of $6,350, it is not right for the teacher to say that she has $6,350 for the tickets of the children.
