Please put the correct number and if you get it wrong it will come up, negs =/. Last test I got a 7/15. Help!

[DDon1996]

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.

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


But learn to do this **** man:

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.

Can you do it? I'm so confused -___-

[ohiostaterules7]

strong remedial math. go back to 1st grade jr.

[DDon1996]

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.

[Martynator]

Didn't you call out my math skills a while back?
PM me if you still need help

[do13]

An A certainly fits your mathcros.

[DDon1996]

Still not sure if OP knows how to do these problems... Lol.

[FFGtobuff]

alg 2?

[cowmooolester93]

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. Obviously

[Hrad]

Oh yeah this is the guy who nailed his cousin lulz!

$1,048.04

The answer to that question is 1033.71 though.

You have to divide 24.56 by 12 before multiplying it by 5 with your method.

Simple interest is kind of Alg 1 stuff IIRC which was 8th grade and compounding interest was this year.

*realizes he was wrong* oops. Oh ****. How the eff did I graduate haha.

[SomeRandom]

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)

This sounds right. I did this simple/compound stuff in grade 9. Lol writing a math exam today, garuntees 10 pages of graphing and trig equations, with only one of these questions thrown in... Damn

[KevinMK0831]

580 SAT reading
430 SAT math

feels bad man. I never got a good math teacher since 7th grade...
