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 greater than or equal to 1000 , and yes, it is a viable option.

2b−400≤1000 , and no, it is not a viable option.
2 b minus 400 less than or equal to 1000 , and no, it is not a viable option.

To analyze the situation, we need to determine the profit the club can make from selling the candy bars and represent it with an inequality.

  1. Selling Price: Each bar is sold for $2, so if \( b \) is the number of bars sold, the total revenue from selling \( b \) bars is \( 2b \).

  2. Cost: The club spent $400 to buy 725 bars.

  3. Profit: The profit can be calculated as the total revenue minus the cost, which is: \[ \text{Profit} = \text{Total Revenue} - \text{Cost} = 2b - 400 \]

  4. Requirement for Profit: The club needs to make at least $1,000 in profit to go on their trip: \[ 2b - 400 \geq 1000 \]

Now let’s simplify this inequality to find out how many bars need to be sold to meet the profit requirement: \[ 2b - 400 \geq 1000 \] Adding 400 to both sides: \[ 2b \geq 1400 \] Dividing both sides by 2: \[ b \geq 700 \]

This means the club needs to sell at least 700 bars to achieve a profit of $1,000.

  1. Viability of Selling 725 Bars: Since they have 725 bars available and they only need to sell 700 bars, selling 725 bars is indeed a viable option.

Conclusion: The inequality that represents the situation is \( 2b - 400 \geq 1000 \), and yes, it is a viable option.

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