Lisa and Beverly had just $5 to spend for an afterschool snack. They could’ve bought 2 hamburgers and 1 carton of milk with no change back, or 1 hamburger and 2 cartons of milk with 40 cents change back. How much does each carton of milk cost?

Hamburger - 180 cents

Carton of milk - 140 cents

Step-by-step explanation:

Equations:

2h + m = 500 cents

h +2m = 460 cents

Multiply thru the 1st eq. to set it up for elimination:

4h + 2m = 1000

h + 2m = 460

Subtract 2nd from 1st to solve for "h":

3h = 540

h = 180 cents (cost of a hamburger)

Substitute into h + 2m = 460 to solve for "m":

180 + 2m = 460

2m = 280

m = 140 cents (cost of a carton of milk)

if this is really you s much. i only have 3 points left and i have 2 questions to ask

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes.
