Each month for 9 months, Jordan buys 2 sports books. How many more sports books does he need to buy before has bought 25 sports books?
Ok if Jordan buys 2 sports book every month for 9 months
You multiply 9 *2 which is 18
So in those 9 months Jordan bought 18 sports books
If he wants to know how much more he has to buy to have 25 sports books
You subtract 25 -18 which is 7
So Jordan needs to buy 7 more sports books to have 25 of them
He needs to buy 7 more sports book before he bought 25 sports book
Given :
Each month for 9 months, Jordan buys 2 sports books
Each month he bought 2 sport books .
Now we find how many books he bought in 9 months
2 books in 1 month
\(2 \cdot 9 =18\) sports book bought in 9 months
He needs to buy 25 sport books
He has already bought 18 books .
\(25-18=7\)
so, he needs to buy 7 more books
He needs to buy 7 more sports book before he bought 25 sports book
