Question

The adventure club is selling candy bars to go on their annual outing. The bars sell for $2 a bar. The club bought 725 bars for $400. The club needs to make at least $1,000 to go on their trip. Which inequality best represents this problem, and are the 725 bars a viable option to make enough profit?(1 point)
Responses

2b−400≤1000 , and yes, it is a viable option.
2 b minus 400 less than or equal to 1000 , and yes, it is a viable option.

2b−400≥1000 , and no, it is not a viable option.

Answer 1

To determine the inequality that best represents the problem, let's break it down:

1. The club sells candy bars for $2 each, so if they sell \( b \) bars, their revenue can be represented as \( 2b \).
2. The club's total cost for the bars is $400.
3. To check if they can make at least $1,000, we set up the equation for profit, which is represented as:
\[
\text{Profit} = \text{Revenue} - \text{Cost} = 2b - 400
\]
4. The requirement is that the profit should be at least $1,000, so we can set up the inequality:
\[
2b - 400 \geq 1000
\]

Now, we can rearrange the inequality to see if the option to sell 725 bars is viable:

\[
2b - 400 \geq 1000 \\
2b \geq 1000 + 400 \\
2b \geq 1400 \\
b \geq 700
\]

Since the club has 725 bars, we plug this into \( b \):

\[
725 \geq 700
\]

This inequality is true, which means that selling 725 bars is indeed a viable option.

Therefore, the correct response is:
**2b - 400 ≥ 1000, and yes, it is a viable option.**
