Answer:
R=5.5%, P=$1000, T=5yrs
I=PRT/100
I=5.5×1000×5/100
I=$275.00 for the account one, the account two will be $250.00 by comparing, the account one is close to the interest
Remove the radical by raising each side
6^2= square root 8x-4 ^2
36= 8x-4
40= 8x
X=5
To solve this, you would first add the amount of the 3 checks they wrote together. So, 74+132+48=254. Then, we know that they had $317 in their checking account. Now, you would take the amount they had in their account (317), and subtract it by the total of the 3 checks they wrote (254).
The checking account balance is 317-254=63, so $63 is their checking account balance.
I really hope this helps you.
Assuming you're working in base 10, then the antilog of 3.493 is equal to 10^3.493 = 3,111.71633710601
This rounds to 3111.7163 so the answer is choice D
