Answer 1

To determine how many bottles the store owner needs to sell to earn at least $400 in profit, we can use the following formula:

Profit = Profit per bottle × Number of bottles

In this case, the profit per bottle is $2, and the target profit is at least $400.

Let \( x \) be the number of bottles sold. We can set up the inequality:

\[ 2x \geq 400 \]

Now, divide both sides by 2:

\[ x \geq 200 \]

This means the store owner needs to sell **at least 200 bottles** to earn a profit of at least $400.

So the correct response is:

**at least 200 bottles**.
