Answer:
81
Step-by-step explanation:
Answer:
I'm not sure if you meant that when you said "divided by 4"
Given:
Principal (P)= $1,000
Rate of interest (R)= 4% = 0.04
Simple interest (I)= $100
To find:
The time for which she deposits $1000 into a savings account at 4% simple interest.
Solution:
The formula for simple interest is
![I=P\times R\times T](https://tex.z-dn.net/?f=I%3DP%5Ctimes%20R%5Ctimes%20T)
On substituting P=1000, R=0.04 and I=100 in the above formula, we get
![100=1000\times 0.04\times T](https://tex.z-dn.net/?f=100%3D1000%5Ctimes%200.04%5Ctimes%20T)
![100=40T](https://tex.z-dn.net/?f=100%3D40T)
Divide both sides by 40.
![\dfrac{100}{40}=T](https://tex.z-dn.net/?f=%5Cdfrac%7B100%7D%7B40%7D%3DT)
![2.5=T](https://tex.z-dn.net/?f=2.5%3DT)
Therefore, the required time is 2.5 years.
1500 * 2^x
ka^0 = 1500
k = 1500
ka^2 = 6000
a^2 = 6000/1500=4
a=2
