You purchase 2 action figures per week. You have 48 action figures, which is 75% of the total number of action figures you need
balandron [24]

Answer:

64

Step-by-step explanation: In order to find the amount of action figures needed to complete your collection, you divide 48 by 75%. This gives us 64. The reason we divide, is because of inverse operations. If we are going to find 75% of 48, you would multiply 48 by .75. Since this is the opposite, we must divide it.

Also, I'm not quite sure what the question is requesting by asking for what 2 represents. What is the specific skill you are learning in class? Maybe that'll help us figure it out.

I hope this makes since. Let me know if you need further explanation.
