A primary school has 138 children who are raising money for charity. The average amount raised per child is $2.10. The teacher has promised a special sticker for every child who raises $5 or more. She has 60 special stickers. Is that going to be enough? Yes. No. Maybe, or maybe not; there is not enough information to decide.

probably maybe or maybe not

OpenStudy (anonymous):

u r not sure?

OpenStudy (anonymous):

as 2.10=sum of all money/138

OpenStudy (anonymous):

then?

OpenStudy (anonymous):

then divide sum of all money to 60

OpenStudy (anonymous):

sorry

OpenStudy (anonymous):

divide to 5

OpenStudy (anonymous):

the answer will be 57.96

OpenStudy (anonymous):

so 60 is enough

OpenStudy (anonymous):

as it is free choice for children whether they should give money, so we must consider those who gave 0 dollars

OpenStudy (anonymous):

the answer is YES
