Given:
Deposit = $7500
Rate of interest = 2.75%
Time = 4 years
Compounded monthly
n = 12
To find:
The balance in the account after 4 years
Solution:
Compound interest formula:

Here P = $7500, r = 2.75%, n = 12 and t = 4.

To convert percentage into fraction, divide by 100.





The balance in his account after 4 years is $8371.03.
That would be a circle whose radius is 12 miles
= pi * 12^2 = 144pi = 452.4 sq miles to nearest tenth.
So you're saying |5x+2|=x-4?
Yeah, no there is no Solution.
I believe the answer would be: x=30
