To define the inequality that represents the problem, we need to consider the revenue generated from selling the candy bars and the cost incurred.
- Selling price per bar: $2
- Number of bars: 725
- Cost of buying the bars: $400
- 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: \[ 2b - 400 \geq 1000 \quad \text{and yes, it is a viable option} \]
