Michael went to the library for the first time on September 3rd. Andi went every 2 days, Nathan every 3 days, and Michael every 4 days. They ask how many times each person went alone and together during September. Bondan and Samantha play badminton every 4 and 5 days respectively and played together for the first time on August 7th. They are asked when they will play together again. The test questions involve calculating scores based on multiple choice answers and operations with fractions, exponents, and algebraic expressions.
