there are 1000 grams in 1 KILOgram.
therefore in 23.24/kg can be just written using grams as 23.24/1000, since 1kg = 1000 g.
so the price of the chicken per gram is then 23.24/1000 or $0.02324 per gram, roughly 2 and 1/3 pennies per gram.
and the turkey is 5.17/250 in grams already, that gives us $0.02068 per gram, which is roughly 2 pennies.
well, their price difference is 0.02324 - 0.02068, which is 0.00256 per gram unit.
since we know there are 1000 grams in 1 Kg, how much is that for 1000 grams or a Kg? 0.00256 * 1000 or $2.56.
