800 candy bars must be sold to make a profit of $700
Step-by-step explanation:
Members of the band are selling candy bars to raise money
The director uses this equation to calculate the amount of profit p,
made from selling n candy bars p = 1.50 n - 500
We need to find the number of candy bars must be sold to make
a profit of $700
1. Write the equation
2. substitute p by 700
3. solve to find n
∵ p = 1.50 n - 500
∵ p = $700
∴ 700 = 1.50 n - 500
- Add 500 for both sides
∴ 1200 = 1.50 n
- Divide both sides by 1.50
∴ n = 800
∴ The number of the candy bars is 800
800 candy bars must be sold to make a profit of $700
