Hi easybee41,

I misread your question on properties. The property for the question you posted is the commutative property.

Anyway, for this questioin on variables the Independent variable would be the kids. The Dependent variable would be the money made.

This is all a matter of terminology. Independent means that the variable status will not be changed by any other variable present. It can change independently. In the question above, Pam can't determine how many kids she can receive (well she could refuse to babysit certain kids but let's pretend she can't). So literally, the more kids she receives, then the more money she makes.

Money is dependent  on the variable kids. The status of money does NOT change unless the amount of kids changes first. 

================================================================================

Here is some supplemental info that can help you understand variables.

If you wanted to turn this into an equation you would make kids = x and money = y so...

2y= x   (assuming Pam makes $0.5 for every kid she babysits)

To make it look a little more friendly you could say Pam babysat x amount of kids plus 5 more. This would look like:

2y = x + 5.

All you would have to do is fill in the x (it would be given to you or you would have enough info to solve it).

For example if x = 4. Then she babysat 4 kids plus 5 more which would be 9 kids.

2y = 9 

y = 4.5   (so $4.5)

================================================================================

Now does that help you? If so can you choose my answer as the best answer please? Thanks easybee. Sorry for the other question on properties that you posted. I promise I am better in math than that lol. If you ever need anymore help you can feel free to ask me directly. Take care.
