Determine the unit rate for 1 bag of chips if 5 bags cost $6.25; the proportional relationship is described by 5y = $6.25x

The equation 5y = $6.25x represents a proportional relationship, where x is the number of bags and y is the cost in dollars.

To find the unit rate for 1 bag of chips, we can divide both sides of the equation by 5:

y = $6.25/5x

Simplifying, we find that the unit rate is:

y = $1.25x

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