$10 here would do quite a lot.
As a student in my final year, $10 would cater for my upkeep for about a week or two. It could also cater for some educational needs like; photocopy of materials, printing of online notes, and settling of some compulsory academic dues.
Finally, $10 would buy me a new multimeter which is a major equipment needed for my final year project and some other extra equipment.
Here in Nigeria, $10 means quite a lot for the common student.
