Question

a school principal orders 75 boxes of chalk. each box has 12 sticks of chalk, the school has 23 teachers. Does the principal have enough chalk to give each teacher 40 sticks? if yes, how many sticks are left over? if no, how many more sticks does the principal need?

Answer 1

Well 75x12=900 so 900 divided by 40 is 22.5 so 22 teachers can have 40 chalks but the principal needs to order another 20 :)
