A single-serving carton of yogurt costs 73 cents. A case of 8 single-serving cartons costs $5.36. How much is saved per carton by buying the yogurt by the case?

Answer 1

Eva Abramson

By buying the case, each carton will cost #6# cents less.

If a case of #8# single-serving yoghurt cartons costs #$5.36#, then the price of a single carton in the case will be:

#x=5.36/8#

#x=0.67#

Since a single-serving carton costs #$0.73#, the saving (#y#) per carton by buying the case will be:

#y=0.73-0.67#

#y=0.06#
