Y=A(B)^x
Y is the final amount
X is the amount of time
B is the rate of change.
A is the initial amount.
The compounding formula is Y=A(1+ r/n)^nt
Where n is the number of times compounded, t is the amount of time, a is the inital value, r is the rate of change, and y is the final value.Log: http://forum.bodybuilding.com/showthread.php?t=159714881&p=1213186101

You can solve most of them with that calculator. I solved this one just as a test:
Tonya purchased a building for $295,150. The land appreciates about 5.6% each year. What is the value of the land after 17 years?
Answer
$745,297.04
$110,806.87
$319,460.14
$576,132.80

Okay, look:
Galvin has deposited $879 in a savings account that earns interest at a rate of 1.8% compounded quarterly. What will the account balance be in 14 years?
Y=A(1+r/n)^nt
with the variables as defined in my first post.
Y=879(1+.018/4)^4(14)
y=1130.3
$894.82
$1,582.20
$1,130.28
$2,387.07
The logical choice would be C.
That's compounded.
Simple is much easier:
Y=A(B)^x
Malory purchased a car for $21,825. It depreciates about 5.8% each year. What is the value of the car after six years?
Y=21,825(.942)^6
(The .942 comes from 1.058).
Y= 15,250
Answer
$21,199.67
$15,249.64
$30,610.35
$14,229.90
Logical choice would be B.Log: http://forum.bodybuilding.com/showthread.php?t=159714881&p=1213186101

The Socialist Party candidate for President of the US, Norman Thomas, said this in a 1944 speech: "The American people will never knowingly adopt socialism. But, under the name of "liberalism," they will adopt every fragment of the socialist program, until one day America will be a socialist nation, without knowing how it happened."

il try to help bro.
Timothy deposited $1,023.48 in a savings account that earns 2.4% simple interest. What will Timothy’s account balance be in 5 months?
Answer
you gotta set it up like this (oh btw not the real way to do it BUT it gets the answer) also takes longer. but since u didnt get the formula.
you want to find out what 2.4% of 1,023.48 is. so 1,023.48  2.4%
____________________________________________ ?  100%
1,023.48 * 2.4 = 2,456.35. Then you divide 2,456.35 / 100 = 24.56
24.56 * 5 (months) = 122.81 then 1,023.48 + 122.81 = 1,146.29
$1,023.48
$1,033.71
$1,048.04
$1,146.30 is your answer. Round it. ObviouslyI have CF(genetic disease) hence my super small size.

Different curriculum I suppose. I haven't seen compounding interest yet, and I don't remember even looking at simple interest. Have been taking highest available levels of math for the first two years of HS too.. (without going into sr. classes)
