The unit ratio is defined as the total cost divided by the number of oz.
So, the large popcorn has a unit cost of
[tex] \dfrac{1.12}{16}=0.07 [/tex]
meaning that 1oz of pop corn costs 7 cents.
Similarly, the small popcorn has a unit cost of
[tex] \dfrac{0.96}{12}=0.08 [/tex]
meaning that 1oz of pop corn costs 8 cents.
So, the large popcorn has a lower unit rate.
