Final answer:
Duane Coldren's total deposit, after adding the checks and calculating the cash to be withdrawn, equals the sum of the checks since the cash received is part of the deposit. The total deposit is, therefore, $431.91 (Option C).
Step-by-step explanation:
To find Duane Coldren's total deposit, we first need to add together the values of the checks he has, which are $343 and $88.91. Adding these two amounts gives us a subtotal before he receives any cash back.
$343 + $88.91 = $431.91
Next, we determine the total value of the cash he wishes to receive: 7 ten-dollar bills, 4 one-dollar bills, 9 quarters, and 15 dimes.
- 7 ten-dollar bills = $70
- 4 one-dollar bills = $4
- 9 quarters = $2.25
- 15 dimes = $1.50
Let's add up the total value of the cash to be received:
$70 + $4 + $2.25 + $1.50 = $77.75
Since he wishes to receive this amount in cash, we need to deduct it from the subtotal to find out the total deposit after receiving cash back.
$431.91 - $77.75 = $354.16 (not listed in the options provided)
However, since $354.16 isn't one of the provided answer choices and we should include the cash received as part of the deposit, we'll consider the initial sum of the checks as the total deposit, which is $431.91 (Option C).
