hi , there is this book i borrowed at national library, and i love it so much that i would like to share with you.


It is called Sing to the Dawn.It is a story about a girl who wants to go to the city to study when she wins a competition.It was everyone’s to go to the city to study as they can study more things there and come back to the village to improve the lives of the villages.Her father did not want her to go,but wanted her brother who was in second place to go instead.

Hope you like it.

Can somebody please help with this question?


Among the 200 dollar notes that a cashier collected, some were two-dollar notes and the rest were five-dollar notes. The total value of the two-dollar notes was $230 less than that of the five-dollar notes, how many two-dollar notes did the cashier collect?

I tried to find how many more five-dollar notes were there,and minus the extra from the total.Then,I divided by two.However it is wrong. :scratchhead:

Thanks.
