Slimp's bookstore receives a box of books from each of five paperback publishers. each box contains 21 different titles. the store manager decides there is room to display 4 books from each of 3 of the publishers. how many ways can the display be chosen?

There are 59850 ways to chose the display.

Step-by-step explanation:

Since we have given that

Number of paperback publishers = 5

Number of titles each box contains = 21

Number of books display = 4

Number of publishers he needed = 3

So, the number of ways to select the 3 publishers from 5 is given by

Number of ways to select the books from the different books is given by

Hence, total number of ways that the display can be chosen is given by

Hence, there are 59850 ways to chose the display.

thats not a system of equations, that is a solution
