If you have $10 in your wallet, and you give $3 to your best friend, how many dollars do you have left?

If I have $10 in my wallet and I GIVE $3 away, this would be a simple subtraction problem. Set it up like this: 10-3=? 10-1=9 9-1=8 8-1=7 So.... 10-3=7! You have $7 left after letting your friend have $3.

List and define the main three concepts of Freud's psychoanalytic theory? Provide at least one example using each of these three concepts.

Id: Primitive and instinctual part of our brain, generally selfish and disorganized Superego: Morals and principles, like your conscience Ego: Moderates between the Id and Superego, realistic , organized, and perceptual For example: You really want the new iPhone that just came out. Id: Tells you to take it from the Apple store because you want it. Superego: Tells you that it is wrong to steal and you do not need it that bad. Ego: Reminds you that you can just save up for it to buy it yourself as opposed to stealing it.

A new music subscription service (we'll call this app "Music Time") has just been introduced into the app store. Music Time charges $10 a month plus $0.10 per song you save to your device. You notice your Music Time bill at the end of the month was $33. There's another subscription service called "Noise Sky" that is more popular. They charge a rate of $5 a month plus $0.12 per song but you can only save 300 songs maximum a month. 1. Write out each equation that would best work to solve this problem. 2. How many songs did you end up saving in this first month using Music Time? 3. Which service is the better deal? Music Time or Noise Sky?

1. s=number of songs saved with Music Time .10s + 10 = 33 .10s + 10 - 10 = 33 -.10 (.10s/.10)=23/.10 s= 230 n= total spent on Noise Sky for same amount of songs as Music Time .12(230) + 5 = n 27.6 + 5 = n 32.6= n 2. s=230 230 total songs were saved 3. Noise Sky is the better deal. For the same amount of songs (230) you save $.04 using Noise Sky compared to Music Time.
