MAD=1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|)
=1/8(|26-24|+|22-24|+|31-24|+|18-24|+|24-24|+|22-24|+|19-24|+|30-24|)
=1/8(2+2+7+6+0+2+5+6))
=3.75
The MAD is 24.

Answer:
$20.01
Step-by-step explanation:
In 2004–2012, the interest rate is 0.002%. In 2013, it is 0.004%. In 2014–2021, the interest rate is 0.002%. That is, in the 18 years between 2004 and 2021 (inclusive), the interest rate is 0.002% for 17 of them. The effective account multiplier is ...
(1.00002^17)(1.00004^1) = 1.00038006801
Then the account balance is ...
$20 × 1.00038006801 ≈ $20.01
_____
<em>Additional comment</em>
The annual interest earned on $20.00 is $0.0004. If the account balance is rounded to the nearest cent annually, at the end of the 18 years, the balance will still be $20.00. Not enough interest is earned in one year to increase the balance above $20. At the end of the 18 years, the amount of interest earned is 0.76¢ (a fraction of a penny) <em>only if there is no rounding in intervening years</em>.
Answer:
Cash (2.00% × $770,000) = $15,400
Interest revenue (2.50% × $690,000) = $17,250.
Discount = 770,000 - 690,000 = 80,000
