Answer:
Savings per can would be 0.02 cents when purchased in lots.
Step-by-step explanation:
Given:
Ordinary price of soup 2 cans = 0.33 cents.
When purchases in lots 12 cans = 1.74
We need to find the saving per can when purchased in Lots.
Solution:
Ordinary price of soup 2 cans = 0.33 cents.
1 can = Cost of 1 can when purchased ordinary.
By Using Unitary method we get;
Cost of 1 can when purchased ordinary = 
Now we will find the Cost of 1 can when purchased in lot.
12 cans = 1.74
1 can = Cost of 1 can when purchase in lot.
Again by using Unitary method we get;
Cost of 1 can when purchase in lot = 
Savings = Cost of 1 can when purchase in lot - Cost of 1 can when purchased ordinary
Savings = 
Hence Savings per can would be 0.02 cents when purchased in lots.
