Which cheese is the better price?
At first glance it seems to be the one on the left, with a unit price of $6.65 vs the one on the right with a unit price of $9.56.
But on closer look, the cheese on the right is about 30% cheaper at $.30 an ounce vs $.42 an ounce for the one on the left (8 oz for $2.39 vs 12 oz for $4.99).
Where is the error?
Take a look at the "unit" in each case:
Can't wait to see the price by kilometer.
