It will take 12.8047 years for Jari's investment to double
Step-by-step explanation:
The formula for compound interest, including principal sum is
, where:
- A is the future value of the investment/loan, including interest
- P is the principal investment amount (the initial deposit or loan amount)
- r is the annual interest rate (decimal)
- n is the number of times that interest is compounded per unit t
- t is the time the money is invested or borrowed for
Jari invests in a CD with an annual interest rate of 5.45% compounded quarterly. We need to find how many years it will take for Jari's investment to double.
∵ The annual interest rate is 5.45%
∴ r = 5.45% = 5.45 ÷ 100 = 0.0545
∵ The interest rate is compounded quarterly
∴ n = 4
∵ The Jari's investment is doubled in t years
∴ A = 2P
- Substitute these values in the rule above
∵
- Divide both sides by P
∴
∴
∴
- Insert ㏒ to both sides
∴
- Remember
∴ ㏒(2) = 4t ㏒(1.013625)
- Divide both sides by 4 ㏒(1.013625) to find t
∴ t = 12.8047 years
It will take 12.8047 years for Jari's investment to double

Answers
Answer:
6 pounds.
Step-by-step explanation:
70-25.36= 44.64 (the amount of money she spent)
44.64/7.44 (per pound cost)= 6
Answer:
Rachel bought 6 pounds of coffee.
Step-by-step explanation:
First, do $70-$25.36, because that will give you the total amount of money she spent on coffee.
$70-$25.36= $44.64.
Rachel spent $44.64 on coffee.
Next, you know that every pound of coffee costs $7.44.
So, $7.44x = $44.64
x= the number of pounds of coffee Rachel purchased.
So, we have to now isolate x.
$7.44x / $7.44 = $44.64 / $7.44
x= 6
Therefore, Rachel purchased 6 pounds of coffee.
