40 pts help Each month, Jason wants to save money for a mini IPAD. The mini IPAD cost $800. Jason has $120 and can save $40 a month. The function f(x) = 40x + 120 can be used to represent the number of months and f(x) represents amount of money saved.

Part 2: How much money will Jason have saved after 3 months? Use function notation to show your thinking.


Part 3: How much more will he still need to save in order to buy the iPAD mini?
