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

Answer 1

To find the unit rate, we need to calculate the cost of 1 bag of chips.

From the proportional relationship given, we know that 5 bags cost $6.25. So, we can set up the equation:
5y = $6.25

Now, we can isolate y (the cost of 1 bag) by dividing both sides by 5:
y = $6.25 / 5
y = $1.25

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