Your statement is a little ambiguous due to type mistake, so I am assuming you meant to say:
'if 12 fl. oz. bottles cost $84 how much does one bottle cost? Find the Unit Rate.
so I am solving based on '12 fl. oz.' bottles costing $84.
Answer:
unit rate = 7 $ per fl. oz.
Therefore, the 7 $ per fl. oz is the unit rate.
Explanation:
We know that a unit rate is basically a fraction (also called ratio) between two different units with a denominator of 1.
For example, kilometers per hour, and heartbeats per minute, etc.
Here, I assume, by 'unit rate' means you mean to say 'cost per fl. oz.'
Given
The cost of 12 fl. oz. bottlers = cost $84
The cost of 1 bottle cost = $84 ÷ 12 oz = 7 $ per fl. oz.
Hence,
unit rate = 7 $ per fl. oz.
Therefore, the 7 $ per fl. oz is the unit rate.
