Answer:
2¢ per can
Step-by-step explanation:
You want to know the savings per can of soup purchased at $1.74 per dozen instead of 2 for 33¢.
Per can
The cost per can is found by dividing the cost by the corresponding number of cans:
33¢ for 2: $0.33/(2 cans) = $0.165/can
$1.74 for 12: $1.75/(12 cans) = $0.145/can
Difference
The difference in cost per can is ...
$0.165 -0.145 = $0.02
The savings per can is 2 cents when purchased in lots of a dozen.
