Question 1084270: It is tempting to try to solve an inequality like an equation. For instance, we might try to solve 1<3/x
by multiplying both sides by x, to get x < 3, so the solution would be (-∞ ,3)
But that’s wrong; for example, x = -1 lies in this interval but does not satisfy the original inequality. Explain why this method does not work. In addition, solve the inequality correctly. Please be sure to explain your reasoning!

Question 1084563: The question is:
Hannah invests $4500 in an investment with an APR of 5.2% compounded monthly. She also makes a monthly deposit of $200 per month into this same investment. What is the total amount of money in this investment after 3 years?
I tried the savings formula: 4500 * ((1+(.052/12)^(3*12)-1) / (.052/12)
which didn't have anywhere to fit the $200 in, and also got me 0 as an answer. What formula should I use?

Question 1084573: Here's the question I'm working on:
The percentage of Republicans in the House of Representatives decreased from 53.3% in 2007 to 46.4% in 2009.
By how many percentage points did the percentage of Republicans in the House drop between 2007 and 2009? What was the percentage decrease of the percentage of Republicans in the House of Representatives between 2007 and 2009?
For the first part, I did: 53.3% - 46.4% =
6.9 %pts
For the second part, my math was:
.464 - .533= .069
.069/.533 = .12945590 =
-12.95%
Is this the correct way to do it? Thank you in advance!
