Answer:
-4
Step-by-step explanation:
Assuming that the following equation is correct, begin by solving the operations within parentheses and absolute value expressions.
|3 - 8| -
|-5| -
The absolute value of -5 is 5; -5 is five units away from 0. 12/4 is equal to 3.
5 -
5 - 9 = -4
The simplified expression is equal to -4.
Answer:
$6370
Explanation:
The simple interest formula gives us the final amount A given the principal amount P:
where r is the interest rate and t is the time interval.
Now in our case we have
P = 2800
r = 4.25/100
t = 30 years
therefore, the above formula gives
which simplifies to give
Hence, the account balance after 30 years will be $6370.
