Hi Pratima,
This is a good math problem to solve when figuring out cost per serving per person.
If bacon is $1.92 per pound and each pound is 14 slices, you can figure out the per slice price and the per serving price:
$1.92 divided by 14 slices = $0.14 per slice of bacon
$0.14 per slice times 3 slices = $0.42 per serving of 3 slices.
