Marvin has 4 books to read for homework this week if he reads 2/3 of a book each night how many nights will it take him to read all 4 books

i believe it's 6 nights

First, we can break down his pay into how much he gets each month. There are 12 months in a year so lets break his salary down into 12 payments :

71,000 / 12 = 5916.67

Now, if he receives a paycheck twice a month, we need to breakdown his monthly payment into 2. Thus, his bi-monthly paycheck is :

5916.67 / 2 = 2958.33
