To determine the correct inequality and whether the 725 bars are a viable option for the adventure club, let's break down the information given.
- Cost of the bars: The club bought 725 bars for $400.
- Selling price: Each bar sells for $2.
- Desired profit: The club needs to make at least $1,000.
Step 1: Calculate Revenue
Let \( b \) be the number of bars sold. The revenue generated from selling \( b \) bars is: \[ \text{Revenue} = 2b \]
Step 2: Calculate Profit
The profit can be determined by subtracting the cost from the revenue: \[ \text{Profit} = \text{Revenue} - \text{Cost} = 2b - 400 \]
Step 3: Set Up the Inequality
To find how many bars they need to sell to make at least $1,000 in profit, set up the inequality: \[ 2b - 400 \geq 1000 \]
Step 4: Solve the Inequality
Add 400 to both sides: \[ 2b \geq 1400 \] Divide by 2: \[ b \geq 700 \]
Step 5: Determine if 725 Bars is Viable
Since the club has 725 bars, we check if this amount meets the requirement:
- The number of bars they can sell (725) is greater than 700 (the minimum required) which means they can indeed make enough profit.
Conclusion
Now, let's summarize the responses: The correct inequality is: \[ 2b - 400 \geq 1000 \]
And, since 725 bars is enough to meet the desired profit: Yes, it is a viable option.
Thus, the correct response is: 2b−400≥1000 , and yes, it is a viable option.
