Three students were saving money to buy Christmas presents. Luciano saved the same amount each week. She made this to table to show how much she saved. 
Suhani wrote the equation T= 10w to show how much she saved. In the equation, T represents the total amount of money saved and w is the number of weeks.

Justin made a graph to represent how much he saved per week.
Which student saved the greatest amount of money each week?_______ 
Which student saved the least amount of money each week?_______
