• What porperty can you use to make it easier to find the total cost of different gifts?
• What number do you compare to the total cost of each plan to decide whether it is affordable?
+249 Plan 1: 22*3 = 66, so she can afford plan 1.
Plan 2: 29.26+23.99+23.74 = 76.99, so she can not afford plan 2.
Question 1: The associtative property of addition (when adding 3 numbers, it doesn't matter which numbers you add first: (a+b)+c = a+(b+c).
Question 2: The maximum amount of money she can spend, which is $75.

+73 Thanks but what about the others questions?

+73 Now that better, thanks!!! Oh and just for correcting you. Question 2 is worng! The answer is to compare the total cost of each plan. So for the DVDs total cost is $66 and for the different gifts is $76.99 so if you compare those two you see that she can afford the DVDs.
