To determine which candy bar is the better buy, we need to analyze the cost of Candy Bar A from the table you mentioned (though the specific costs are not provided in your question), and compare it to the cost of Candy Bar B given by the equation \( y = 1.30x \).

Let's assume:

  • \( x \) is the number of bars.
  • For Candy Bar B, the cost increases linearly as more bars are purchased at a rate of $1.30 per bar.

To compare:

  1. First, find the cost per bar for Candy Bar A. If you know the total cost for a specific number of bars, divide that total by the number of bars to get the cost per bar.

    \[ \text{Cost per bar of A} = \frac{\text{Total cost of A}}{\text{Number of bars of A}} \]

  2. For Candy Bar B, since the cost per bar from the equation \( y = 1.30x \) can be simplified to:

    \[ \text{Cost per bar of B} = \frac{1.30x}{x} = 1.30 \]

    So, the cost per bar for Candy Bar B is $1.30.

Conclusion:

  • If the cost per bar of Candy Bar A is less than $1.30, then Candy Bar A is the better buy.
  • If the cost per bar of Candy Bar A is equal to $1.30, then both are the same.
  • If the cost per bar of Candy Bar A is greater than $1.30, then Candy Bar B is the better buy.

Without the specific cost of Candy Bar A, it’s impossible to definitively answer the question. You would need to check the given costs for Candy Bar A and compare them to $1.30 to determine the better buy.
