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

**Steve**, Wednesday, June 18, 2014 at 11:37amThe 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 ...
