The Sojourn family starts with $2000 and spends $150 daily. After **x** days, the total amount spent is **150x**. The remaining money is calculated by subtracting the total spent from the initial amount:
**2000 − 150x**.

- **Option A (1850x)**: Incorrect, as multiplying the first day's remaining amount by **x** does not represent the correct pattern.
- **Option B (2000 − 150x)**: Correct, directly subtracts total spending from the initial amount.
- **Option C (150x)**: Only represents total spending, not the remaining money.
- **Option D (2000 + 150x)**: Implies adding money, contrary to spending.

Explanation:
The Sojourn family started with $2000. If they spend $150 each day, after x days, they will spend a total of $150x.

To find out how much money they have left after x days, you need to subtract the total amount spent ($150x) from the initial amount ($2000).

So, the expression that represents how much money they had after x days is:

$2000 - 150x$

This matches option B.
B
zhipu B. 2000 − 150x

Explanation: The Sojourn family started with $2000 and spent $150 each day. To find out how much money they had after x days, you need to subtract the total amount spent (which is $150 multiplied by x days) from the initial amount of $2000. The correct expression for this is 2000 − 150x. Therefore, the correct answer is B.

deepseekv3 To determine how much money the Sojourn family has after \( x \) days, we start with their initial amount of \$2000 and subtract the amount they spend each day.

- **Initial amount**: \$2000
- **Daily spending**: \$150 per day
- **Total spending after \( x \) days**: \( 150x \)
- **Remaining money after \( x \) days**: \( 2000 - 150x \)

Thus, the correct expression is \( 2000 - 150x \).
