Answer 1

To determine which candy bar is the cheapest cost per bar, we need to find the cost per unit for both Candy Bar A and Candy Bar B.

1. Candy Bar A:

   • We can calculate the cost per bar for different quantities:
     • For 1 bar: Cost = $1.25 → Cost per bar = $1.25 / 1 = $1.25
     • For 2 bars: Cost = $2.50 → Cost per bar = $2.50 / 2 = $1.25
     • For 3 bars: Cost = $3.75 → Cost per bar = $3.75 / 3 = $1.25
     • For 4 bars: Cost = $5.00 → Cost per bar = $5.00 / 4 = $1.25
     • For 5 bars: Cost = $6.25 → Cost per bar = $6.25 / 5 = $1.25

   So the cost per bar for Candy Bar A is consistently $1.25.

2. Candy Bar B:

   • The equation representing the cost of Candy Bar B is \(y = x\). This means that the cost is equal to the quantity purchased:
     • For 1 bar: Cost = $1 → Cost per bar = $1 / 1 = $1
     • For 2 bars: Cost = $2 → Cost per bar = $2 / 2 = $1
     • For 3 bars: Cost = $3 → Cost per bar = $3 / 3 = $1
     • For 4 bars: Cost = $4 → Cost per bar = $4 / 4 = $1
     • For 5 bars: Cost = $5 → Cost per bar = $5 / 5 = $1

   So the cost per bar for Candy Bar B is consistently $1.

Now we compare the cost per bar for both:

• Candy Bar A: $1.25 per bar
• Candy Bar B: $1.00 per bar

Conclusion: Candy Bar B is the cheapest cost per bar.

Answer: 2 (for Candy Bar B)
