Explanation:
Question A-
To find: Greatest number of toys that Paul can buy with $2760
We can simply divide the total money by the toy's price-
total money/toy's price
= 2760 / 9
= 306.6
= 306 (since we cannot buy .6 of a toy we round it off to the previous number)
Question B-
To find: Amount of money left after buying the toys
The remanider of 2760/9 will give us the money left with Paul
= $6
