Answer: The total activity based cost for Jacki Marshall during the month is $16 (option A).
We arrive at the total cost for each of Jacki's activities as follows:
[tex]Cost of Teller Transactions = Cost per transaction * Number of transactions[/tex]
[tex]Cost of Teller Transactions = 2.80 * 4 = 11.20[/tex]
[tex]Cost of Cancelled Checks = Cost per cancelled checks* Number of transactions[/tex]
[tex]Cost of Cancelled Checks = 0.25* 12 = 3[/tex]
[tex]Cost of ATM transactions = Cost per ATm transaction * Number of transactions[/tex]
[tex]Cost of ATM transactions = 0.20 * 9 = 1.80[/tex]
[tex]Total cost for Jacki Marshall = 11.2 + 3 + 1.8 = 16[/tex]
