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 for 1 bag of chips, we need to divide the total cost (in this case, $6.25) by the number of bags it represents (in this case, 5 bags).

First, we can rewrite the proportional relationship equation as:
5y = $6.25x

Since we are interested in the unit rate for 1 bag, we need to find x (the number of bags) when y (the cost) equals $1. We can set up the equation for this:
5(1) = $6.25x

Now we can solve for x:
5 = $6.25x
Divide both sides by $6.25:
5 / $6.25 = x

x = 0.8

So, the unit rate for 1 bag of chips is 0.8.
