My van rental is $532.69 for 7 days. 6 of us are paying for 7 days use and 1 is paying for 5 days use since he came later on our trip. I can split the cost evenly between the 7 people but I don't want to over charge my friend who wasn't there for the first two days. Is there a formula I can use? I just want to be fair. Thanks for your help everyone.

I have three price indices (the first starting in 1987, the second in 1991 and the third in 2000). I am trying to construct an aggregate index for all three. I am having trouble because of the different starting date for each index. The problem is that when the second series comes in then the index falls or rises sharply, and the same happens when the third series comes in as well.Could someone please help me out? Thanks

Complete the square.

Everytime I do problems like this or anything that results in a factor with a fraction I get stumped for like 5-10 mins. When it comes to test taking time that'll consume the whole hour of the test, especially with 40 questions!

I understand te concept but I have two questions:
a. Whats the answer
b. How do I get better at factoring out large numbers and fractions

Therefore , 2x + 1 = 2x + 2
