Kasey's job at store is to equally stock the shelves. he need to put 81 bottles of soda on 9 shelves. he sold some bottles from the first shelf. he sold some bottles from the first shelf. he sold 2 bottles to a man and 3 to a lady. how many bottles are remaining on that shelf

If he should put 81 bottles in 9 shelves so in each shelves we have 81 ÷ 9 = 9 bottles so in each shelves is 9 bottles and he sold 2 and 3 of them so he sold 2+3 =5 of them so in that shelf he has 9 - 5 = 4 bottles left so the answer is : he has 4 bottles in that shelf left :)))
i hope this be helpful
* happy new year *

First, we need to find how many were on each shelf. 

81/9 = 9

There are 9 bottles on each shelf.

Now, we need to add 3 and 2.

3+2 = 5

Now, subtract 5 from 9.

9-5 = 4

Final - There are 4 bottles remaining on that shelf.

21, i'm pretty sure it's right lol
