Answer:Option b.Step-by-step explanation:The balance in Debbi's account in the start of the month was = His previous month's balance + Prevoius month's pay = $320.45 + $4300.5 = $4620.95  Now, total expenditure of this month = Pay check + ATM withdrawal + Service charge = $3290.78 + $300 + $5.25 = $3596.03. So, the balance of this month will be $(4620.95 - 3596.03) =$1024.92 But Debbi's new balance is $1873.20. Therefore, the increase in pay is $(1873.20 - 1024.92) = $848.28 was the direct deposit.
