The adventure club is selling candy bars to go on their annual outing. The bars sell $2 a bar The club bought 725 bars for $400The 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) 2b - 400 < 1000 and noit is not a viable option 2b - 400 >= 1000 and yes, it is a viable option 2b - 400 <= 1000 and yes, it is a viable option 2b - 400 > 100% and noit is not a viable option

To define the inequality that represents the problem, we need to consider the revenue generated from selling the candy bars and the cost incurred.

  1. Selling price per bar: $2
  2. Number of bars: 725
  3. Cost of buying the bars: $400
  4. Minimum profit needed: $1,000

To find the inequality, we start by calculating the revenue from selling the bars:

  • Revenue from selling \( b \) bars = \( 2b \)

Next, we need to calculate the profit:

  • Profit = Revenue - Cost
  • Profit = \( 2b - 400 \)

The club needs to make at least $1,000 in profit, so we set up the inequality:

\[ 2b - 400 \geq 1000 \]

Now, we solve the inequality for \( b \):

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

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

Now, let's check if selling 725 bars will yield enough profit:

Calculate the profit if 725 bars are sold:

\[ \text{Profit} = 2(725) - 400 \] \[ \text{Profit} = 1450 - 400 = 1050 \]

Since $1050 is greater than $1000, selling 725 bars is indeed a viable option.

So, the correct choice is: \[ 2b - 400 \geq 1000 \quad \text{and yes, it is a viable option} \]
