Answers:
- a = 8
- r = -15%
- y = 4.9 approximately
Note: your teacher may want you to type in a positive value for r
=========================================================
Explanation:
The given equation y = 8(1-0.15)^t is in the form y = a(1+r)^t
We have a = 8 as the initial value, or what we start with.
r = -0.15 converts to -15%, so we have a decay of 15%
Plug in t = 3 to find the corresponding value of y
y = 8(1-0.15)^t
y = 8(1-0.15)^3
y = 8(0.85)^3
y = 8(0.614125)
y = 4.913
y = 4.9
To find the mean, you add all of the numbers and divide by how many they are. When you add them you get 1112, then divide by 10 and get...
answer: 111.2
