Answer:
2.2%
Step-by-step explanation:
Given the following :
Population in year 2000 (A) = 4.2 million
Expected population every 32 years = 2 *A
The growth rate per year =?
The population figure after 32 years = (2 * 4.2 million) = 8.4 million
Using the exponential growth formula :
P(t) = A × (1 + r)^t
(1 + r) = g = Total growth percent
A = Initial population
t = time
P(t) = 8.4 million
8,400,000 = 4,200,000 × g^32
g^32 = (8400000/4200000)
g^32 = 2
Taking the root of 32 on both sides
g = 1.02189714865
g = (1 + r)
1.02189714865 = 1 + r
r = 1.02189714865 - 1
r = 0.02189714865
.rate = 0.02189714865 * 100
= 2.18971486541%
= 2.2% ( nearest tenth)
I think he would expect $60,000
I hope thats right,

Answer:
The answer is -x+26.
Step-by-step explanation:
First you distribute the -3 into the parthensis and you get -3x+15. You write the whole expression again plus the -3x+15 you got from the distributing part so 8-3x+15+2x+3. You combine the like terms so the x with the x and the numbers with the numbers. From there you get the answer of -x+26. I hope this helps you!
