today we did some math stuff. we learned about half-life and maintenance level. half-life is half the time for half the substance to be gone. maintenance level is when a person ingests a substance at regular time intervals, the amount of the substance in the blood eventually levels off, of stabilizes.

using microsoft excel for sequences

today in class we used a program called microsoft Excel. it was an easier way to find out the answer for sequences in a faster manner. you type in the first couple formulas and titles and from your specific question. ex. =b2*2 or =C2+.5. then scroll to the bottom to find the answer for the specific number your looking for.

today we learned about sequences
sequences are very exciting and fun to do
there are 2 different kinds of sequences
arithmatic sequences are found by adding or subtracting a common number ex: 2,4,6,8
geometric sequences are found by multiplying a common ratio
ex: 2,4,8,16
a recursive formula is based on the preceding term
the formula is tn=tn-1x2
nMin=1st term
u(n)=formula
u(mim)=value of first term
on the calculator

The lesson today was too big for EDLINE, so I posted it here.

Hello Everyone,
I would like to start off by stating that we have a test on Personal Finance on, Thursday April 23rd, 2009. So Study Study Study!!

~***Personal Finance Review***~

Advantages & Disadvantages of Renting & Buying a House.

*** Using TVM Solver***

N: Total Number of payments
I%: annual interest rate as a percent
PV: present value
PMT: payment each period
FV: future value, or accumulated amount
P/Y: number of payments per year
C/Y: number of compounding per year.

TVM Question [Example]
1. Solve for FV (future value)

You decide to invest $6500. The bank offers an interest rate of 8.25% compounded annually. What will your money be worth in 7 years if the interest rate remains unchanged?

N=7 N=7
I%=8.25 I%= 8.25
PV= -6500 PV= -6500
PMT=0 PMT= 0
FV=0 FV= 11321.62307
P/Y=1 P/Y= 1
C/Y=1 C/Y= 1

**It shows that in 7 years your money will be worth $11321.62.**

today we learned about the advantages and disadvantages of leasing.
there are 3 main reasons people lease, rather than buy a new vehicle:
*people who like to drive a new car every few years will pay much less leasing than if they buy. they also don't have to deal with getting rid of their old car, they just turn it in at the end of the lease period.
*lease payments are usually lower than loan payments for any given car.
*leasing gives people the opportunity to drive a more expensive car than they could afford to buy.

There are 3 distinct disadvantages to leasing a car.
first, if you continually lease your cars, you will have never ending payments. if you look forward to paying off your car and owning it free and clear, don't lease.

second, if you decide to buy a car at the lease-end, you'll pay several thousands of dollars more than if you had bought initially. for example, if you buy a car, paying $500 a month for four years, you'll pay a total of $24000. you might be able to lease if for only $400 a month(total payment of $19200), but you'll probably have to pay another$8000 to keep it and if you finance that $8000 you'll pay even more.

third, most leases charge you as much as 25 cents a mile if you exceed the annual limit, usually between 12000 and 15000 miles. if you do extensive driving, leasing probably is not for you.
