ok so what did you try to do ?

lost

i know how to plug in formulas thats about it to be honest

you look for a certain amount of items and find the corresponding t

ok

plug in one for t for everything

no, you want to find t

im 23 this is sad

im 23 as well .. it is fine

but i thought it says t=1 in the problem

:)

no, they say that t=1 means the first week

ahh gotcha

now when you find t , for example if you find t = 10 you know that it is the 10th week in year

now, you got the equation :
n=84.59 + 24.8sin(pi*t/24)

and they ask you for what weeks n = 96,990

i got undefined ...

so it is really should be :
96.99 = 84.59 + 24.8sin(pi*t/24)

since they say "n is in thousands of items"

im getting a crazy calculation

why, look:
96.99 = 84.59 + 24.8sin(pi*t/24)
12.4 = 24.8sin(pi*t/24)
0.5 = sin(pi*t/24)

week 4, week 20, and week 52?

wait ill check :)

yay ur being my life saver right now!!!

THANK U SOO MUCH
