Find the price per egg and compare the two as follows:
dozen = 12
$1.20 / 12 =$0.10 cents per egg at the Super-X store.
$3.15 /(2.5 x 12)
$3.15 / 30 = $.105 cents per egg at the Limitless store.
$0.105 - $0.10 =$0.005 or 1/2 cent per egg cheaper at Super-X store.
5 dozen x 12 = 60
60 x $0.005 =$0.30 - or 30 cents that Sally would save by buying the 5 dozen eggs at Super-X.
