In order to compare the two, we need to find the unit rate for each can. In this case, the unit rate will be in dollars per oz.
For the 28 oz can,
unit rate = $1.89 ÷ 28 = $0.675 / oz
For the 32 oz can
unit rate = $2.95 ÷ 32 = $0.922 / oz
comparing the unit rates, we can see that the unit rate for the 28 oz can is lower (i.e it costs less per oz for the 28 oz can compared to the 32 oz can)
