Answer:
About 7.84 years before the deer population is 400
Step-by-step explanation:
So first we write our equation
125(1.16)^x = 400
Then we divide all sides by 125
1.16^x=3.2
x log 1.16 = log 3.2
06445798922x=0.50514997832
x= 7.83688700862
7.83688700862 years to go!
Answer:
$41,162.71
Step-by-step explanation:
We have the formula to find out the future value of an amount:
FV = PV
when:
- PV is the present value
- r : interest rate or inflation rate
- n is the duration
So that, we substitute PV = $39,500, inflation rate = 3% and duration = 3 into the above fomula, we have:
FV = 39,500x
= 41,162.71 is the amount Kaplans need for their living expenses three years from now
Hope this answer will find you well
Answer:
D
Step-by-step explanation:
The answer is 2/3.
(3^2) (x) + 1 = 3x+5
9x+1=3x+5
Subtract 3x on both sides
6x+1=5
Subtract 1 on both sides
6x=4
Divide both sides by 6 then you get 2/3
