To determine the correct inequality and whether selling 725 bars is a viable option for the adventure club, we first need to set up the inequality based on the information given.
- The total revenue from selling candy bars is represented by \( 2b \) (where \( b \) is the number of bars sold).
- The club's expenses are $400.
- The club wants to make at least $1,000 in profit.
The profit is calculated as total revenue minus expenses, which gives us the inequality:
\[ 2b - 400 \geq 1000. \]
Next, we can solve for \( b \):
-
Add 400 to both sides: \[ 2b \geq 1400. \]
-
Divide both sides by 2: \[ b \geq 700. \]
This means the club needs to sell at least 700 bars to make a profit of at least $1,000.
Now, with 725 bars available for sale:
Since 725 is greater than 700, the club can indeed sell enough bars to achieve their profit goal.
Thus, the correct inequality is:
\[ 2b - 400 \geq 1000 \]
and yes, it is a viable option.
So the correct response is:
2b - 400 ≥ 1000, and yes, it is a viable option.
