Answer
(a) $-\$466.02$
(b) $-\$190.68$
Work Step by Step
(a)
We calculate Ahmad's balance:
$-\$382.45+\$25.10+\$34.50-\$45.00-\$98.17$
$=-\$466.02$
Thus his payment should be $\$466.02$ to achieve $\$0$ balance.
(b)
We start with the balance from (a) and include the new changes ($\$300$ added, $\$24.66$ subtracted):
$-\$466.02+\$300-\$24.66$
$=-\$190.68$
