Answer 1

To find the unit rate for 1 bag of chips, we need to determine the cost of one bag based on the given relationship.

You have the equation \(5y = 6.25x\). Here, \(y\) represents the cost of one bag, and \(x\) represents the number of bags.

To find the cost of 1 bag (when \(x = 1\)), you can first rearrange the equation:

\[
y = \frac{6.25x}{5}
\]

Now, plug in \(x = 1\):

\[
y = \frac{6.25 \cdot 1}{5} = \frac{6.25}{5} = 1.25
\]

Thus, the unit rate for 1 bag of chips is $1.25.

Therefore, the correct response is:

**$1.25**
