Lizzy: A kilogram of pork costs $6 while a kilogram of chicken costs $2 less. How much will a 3-kilogram of chicken and a kilogram of pork cost?.
Me: Hmmm, let me think. I think this is the detailed solution:
A kilogram of chicken costs $6 - $2 = $4. Three kilograms of chicken cost $4 x 3 = $12. So, a 3 - kilogram of chicken and a kilogram of pork cost $12 + $6 = $18. Final answer: 18.
