Giving Change

Create a C# program to return the change of a purchase, using coins (or bills) as large as possible. Assume we have an unlimited amount of coins (or bills) of 100, 50, 20, 10, 5, 2 and 1, and there are no decimal places. Thus, the execution could be something like this:
Enter the price
44
Enter the money given
100
Your change is 56
Number of 50s returned is 1
Number of 5s returned is 1
Number of 1s returned is 1

Several Multiplication Tables

Display a range of multiplication tables, as long as the user asks for... The first input is the start of the range and the second number is the end. For example if you input 2 and then 6, the computer will display the multiplication tables of 2, 3, 4, 5 and 6. The third number represents how many numbers you want in each table. f\or example if you then put the third number as 7, the computer will display the tables from 2 to 6 and the table will go from 2x1 to 2x7 then move on to 3x1 etc.
