i.e. price of one bag of popcorn is to be find out.

Solution:

We can use ratio here to find the rate of one bag of popcorn.

4 bags bought at $3

4 bags : $3

Let us divide both the sides with 4.

`\frac{4}4` bags : $
`\frac{3}4`

OR

1 bag bought at $ 0.75

We can alternatively use unitary method.

4 bags are bought at $ 3

1 bag is bought at $
`(3)/(4)`

1 bag is bought at $0.75.

So, unit rate per bag of popcorn is $0.75.
