Required

Determine the unit rate

To solve this, we simply take any corresponding values of Cost of cookies and number of cookies

When

Cost = $2

Number = 4

`Rate = Cost/Number`

`Rate = \$2/4`

`Rate = \$0.5` per cookie

Pick another corresponding values

When

Cost = $6

Number = 12

`Rate = Cost/Number`

`Rate = \$6/12`

`Rate = \$0.5` per cookie

Hence, the unit rate is $0.5 per cookie

What it represents is that: Every cookie is sold at $0.5
