then try -21.4 that should work
Answer: $7,250
Step-by-step explanation:
5/100 ×$145,000
Answer:
It will take 35.12 years for the account to reach $7,600.
Step-by-step explanation:
Holly invests money, P=$600
Interest rate,r= 7.5%
Amount money,A =$7,600
We know that the formula to obtain the amount
![A=P(1+\frac{r}{100} )^t](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cfrac%7Br%7D%7B100%7D%20%29%5Et)
Where A= Amount money
P= Principle value
r= Interest rate
t= time in years
By using this formula
![7600=600(1+\frac{7.5}{100} )^t](https://tex.z-dn.net/?f=7600%3D600%281%2B%5Cfrac%7B7.5%7D%7B100%7D%20%29%5Et)
![\frac{7600}{600} =(1+\frac{75}{1000} )^t](https://tex.z-dn.net/?f=%5Cfrac%7B7600%7D%7B600%7D%20%3D%281%2B%5Cfrac%7B75%7D%7B1000%7D%20%29%5Et)
![\frac{76}{6} =(\frac{1075}{1000} )^t](https://tex.z-dn.net/?f=%5Cfrac%7B76%7D%7B6%7D%20%3D%28%5Cfrac%7B1075%7D%7B1000%7D%20%29%5Et)
Taking both side logarithm then we get
![log76- log6=t(log1075-log1000)](https://tex.z-dn.net/?f=log76-%20log6%3Dt%28log1075-log1000%29)
1.5798-0.4771=![t(3.0314-3)](https://tex.z-dn.net/?f=t%283.0314-3%29)
By substituting value from log table
1.1027=![t\times 0.0314](https://tex.z-dn.net/?f=t%5Ctimes%200.0314)
By simplification
![t=\frac{1.1027}{0.0314}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B1.1027%7D%7B0.0314%7D)
By division property of equality
t=35.117 years
t=35.12 years ( nearest hundreth place)
Hence, it will take 35.12 years for the account to reach $7,600.
