Katelyn invested $2325 in a savings account which earns 3.45% interest compounded monthly. What will the account be worth in 7 years? $2,959.07 $25,144.92 $2,372.20 $40,159.15
do you have your compounding formula ready?
@amistre64 that one is A = P (1 + r/n) ^ nt right?
yes, thats the perfect one to use
@amistre64 so what do I plug in? I am not good in math
even if we mess up and forgo the n parts, we are only 10 buck off ....
plugging in isnt math, its more like reading comprehension
lol im not good at the either
P is the amount you start with r is the rate in decimal form n is the number of compounding periods in a year t is the number of years
forget n at the moment ... its really not worth it in this setup
okay so p= $2325 r= 3.45 and t= 7
yes, let r = .0345 unless your calculator does % stuff. i never could get that utton to do what it was spose to
Now it looks like A= 2325(1+.0345/n)^n*7
let n=1 or n=12; your choice .... but n=1 isnt going to be that far off
A=2325(1.0345)^7 right?
just for extra stuff to type ... compare the results of 1 year 2325(1.0345) to 2325(1+.0345/12) 1.0345 : 1+.0345/12 1.0345 : 1.002875 1 : .9695 they are practically the same, almost a 1:1 ratio
yes
okay i got 2948.06 but that isn't an answer
youre not looking for THAT answer, your looking for the one thats closest to it ....
A is the closest to it
yes it is :) now if they had all been within a 10 dollar range, then we would have had to go more precise ... but as is the choices wernt really that picky to start with
Thank you so much!!
good luck
