The initial cost is a fixed expense of $800,000. The daily operational cost ($250) and labor cost ($400) sum to $650 per day. Over **D** days, these daily costs amount to **650 × D**. Adding this to the initial cost gives the total cost expression: **800,000 + 650D**.

doubao B. 800,000 + 650D. The total cost is the initial cost of 800,000 plus the daily operational cost of 250 and the labor cost of 400 (which is 650 in total) times the number of days (D). B
minimax To calculate the total cost, we need to consider both the initial cost and the daily costs. The initial cost is a one-time expense, while the daily operational and labor costs are ongoing.

Initial cost: $800,000
Daily operational cost: $250
Daily labor cost: $400
Total daily cost: $250 + $400 = $650

Since the total cost for "D" days would include the initial cost plus the daily costs for each day, the expression would be:

Initial cost + (Total daily cost × Number of days)
$800,000 + ($650 × D)

This matches the format of option B:

B. 800,000 + 650 D

So the correct answer is B.

Explanation:
Terri's total cost consists of three parts:

1. The initial cost to open the restaurant: $800,000
2. Daily operational costs: $250 per day
3. Daily labor costs: $400 per day

So, for each day the restaurant is open, Terri has to pay an additional $250 + $400 = $650.

If the restaurant is open for D days, the total daily costs would be $650 × D.

Therefore, the total cost for opening and operating the restaurant for D days is:
Initial Cost + Daily Costs for D days
= $800,000 + $650D

This corresponds to option B.
B
zhipu To determine the total cost Terri incurs for having her restaurant open for "D" days, we need to account for both the initial cost and the daily costs.

1. The initial cost to open the restaurant is $800,000.
2. The daily operational costs are $250.
3. The daily labor costs are $400.

Combining the daily operational and labor costs, we get:
\[ 250 + 400 = 650 \]

This means the daily cost is $650.

To find the total cost after "D" days, we add the initial cost to the total daily costs over "D" days:
\[ \text{Total Cost} = 800,000 + 650 \times D \]

So, the correct expression is:
\[ 800,000 + 650D \]

This matches option B.

deepseekv3 To determine the total cost for Terri's fast food restaurant, we need to account for the initial cost and the daily operational and labor costs over \( D \) days.

1. **Initial Cost**: \( 800,000 \) (This is a one-time cost.)
2. **Daily Operational Costs**: \( 250 \) per day
3. **Daily Labor Costs**: \( 400 \) per day

The total daily cost (operational + labor) is:
\[ 250 + 400 = 650 \]

So, over \( D \) days, the total daily cost would be:
\[ 650 \times D \]

Adding the initial cost, the total cost becomes:
\[ 800,000 + 650D \]

The correct expression is:
**B. 800,000 + 650 D**
