Answer:
64.5%
Step-by-step explanation:
Initial amount N° = ?
Remaining amount after decay = N = ?
k = decay constant = 0.00012 
t = time = 3650 year
fraction remaining will be N/N°
From the decay equation, N = N°
N/N° = 
N/N° = 
N/N° = 
N/N° = 0.645 = 64.5%
Answer:
$98,048.77
Step-by-step explanation:
First you want to find out how much he has put in without interest so you would do 237.95*12 to figure out how much he puts in per year then times that number by 30 to figure out how much he has put in in total, after this you subtract this total from the 183,710.77 to get the total amount of interest
I'm guessing that the 2 in that is ^2? if so, it opens down.
I’m still thinking about the equation part give me a second
