Answer 1

To find out which candy bar is cheaper per bar, we can calculate the cost per bar for Candy Bar A and compare it to Candy Bar B.

Candy Bar A:

• For 1 candy bar: Cost = $1.25, Cost per bar = $1.25 / 1 = $1.25
• For 2 candy bars: Cost = $2.50, Cost per bar = $2.50 / 2 = $1.25
• For 3 candy bars: Cost = $3.75, Cost per bar = $3.75 / 3 = $1.25
• For 4 candy bars: Cost = $5.00, Cost per bar = $5.00 / 4 = $1.25
• For 5 candy bars: Cost = $6.25, Cost per bar = $6.25 / 5 = $1.25

In all cases, the cost per bar for Candy Bar A is $1.25.

Candy Bar B:

• The equation for Candy Bar B is y = x, meaning the cost is equal to the quantity. Therefore, the cost per bar for Candy Bar B is also $1.00 (since for 1 candy bar it costs $1, for 2 candies it costs $2, etc.).

Comparing the cost per bar:

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

Candy Bar B is cheaper at $1.00 per bar.

The answer is 2 for Candy Bar B.
