Thank you Ashley!!! In order

1: D
2: BCD  (See the note on #6)
3: BC
4: C
5: ACD
6: BCE  (Equations that ARE NOT functions have square roots in them.  If y is to the power of 2, then you have to take the square root to solve it, which makes it not a function.  Remember the graphing packet,  all the functions that were not functions were square root problems)
7: A
8: BD
9: A (square roots only make numbers >= to 0)
10: -3

Int 1:
You have to solve two problems, using the compound interest equations:

A = P(1 + rn )nt

Where:
P = Principal (starting amount)
r = interest rate in decimal
n = # compounding per year
t = time in years

First question: You max out your credit card spending \$1200.  If you have an interest rate of 19%, and do not pay anything, how much will you owe after 6 months?

Second Question.  You won \$2,000,000 in the lottery.  You have to decide where to put your money.  Wells Fargo gives you 2% compounded monthly where as Chase gives you 3% compounded every two months.  Where should you go if you expect to keep your money there for 5 years?
