• Helena lost her marbles. But then she found them and put them in 4 bags with m marbles in each bag. She had 3 marbles left over that didn't fit in the bags.
How many marbles does Helena have in all?

Doesn't losing your marbles mean to go crazy or insane figuratively.
That's why I found this very funny.

• Problem with "Hannah" not clear. Hana is a student or who? if she is a student then it's 127-300/z at the beginning i was thinking that hannah is library owner or something similar and then this expersion will be 127+300 (total books in her collectio)

• Yes, she is a student. If you have enough space in your house, having that many books is not even that impressive. 127 would probably fill one medium sized bookshelf. Also, it wouldn't be 127+300. Her school was going to donate a total of 300. So 300 divided by the number of students would be how many books each student is going to give. Hannah will give that amount, so that is taking away from her collection, subtracting 300/z from her collection.

• You have to write an expression of the information you have. E.g Sunny earns 12 per hour delivering cakes(\$12 per cake). She worked for x hours this week(\$12x). She was charged \$15 for late delivery on Tuesday (-15).
Expression:12x-15
