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

Question

.

Answer 1

To find the unit rate for 1 bag of chips given that 5 bags cost $6.25, you can follow these steps:

1. Identify the total cost and the number of bags:

   • The total cost for 5 bags is $6.25.

2. Set up the unit cost equation:

   • We want to find the cost of 1 bag. If \( y \) is the cost for 1 bag, then for 5 bags, the cost would be \( 5y \).
   • According to the problem, \( 5y = 6.25 \).

3. Solve for \( y \): \[ y = \frac{6.25}{5} \]

4. Calculate the value: \[ y = 1.25 \]

So, the unit rate (cost for 1 bag of chips) is $1.25.
