Answer:
$4,499.46
Step-by-step explanation:
We can use the compound interest formula for this problem:
P = initial balance
r = interest rate (decimal)
n = number of times compounded annually
t = time
First, lets change 4% into a decimal:
4% -> -> 0.04
Now lets plug the values into the equation as shown below:
Don will have $4,499.46 at the end of the three years.
Answer:
It will take 34.33
Step-by-step explanation:
* Lets talk about the compound continuous growing
- Compound continuous growing can be calculated using the formula:
# A = the future value
# P = the initial amount
# r = the growing rate in decimal
# t = the time
* Lets solve the problem
- The population of a particular country is growing at 3.2 %
compounded continuously
∴ r = 3.2/100 = 0.032
- We need to find how long will it take the population to triple
∵ The initial population is P
∴ A = 3P
∵
∴
- Divide both sides by P
∴
- Insert ㏑ for both sides
∴
- Remember
∴ ㏑(3) = 0.032t
- Divide both sides by 0.032
∴ t = ㏑(3)/0.032 = 34.33
* It will take 34.33

Step-by-step explanation:
Answer:
1 7/24.
Step-by-step explanation:
7/8 + 3/4 - 1/3 The LCD of 3,4 and 8 is 24 so we have:
21/24 + 18/24 - 8/24
= 39/24 - 8/24
= 31/24
= 1 7/24.
