The entire band decides to have a concert to raise the money for trip. tickets for the concert will cost $7.50 each. a local business agrees to donate an additional $0.50 for each $1.00 in tickets sales to the band for their trip. what is the least number of concert tickets the band must sell in order to raise the rest of the money needed for the trip?

Given that cost of 1 concert ticket = $7.50

Given that "a local business agrees to donate an additional $0.50 for each $1.00 in tickets sales to the band for their trip."

Donation $0.50 is half of $1. So that means you are getting half of the ticket price as donation

half of $7.50 is $3.75

So the effective collection per ticket = original cost + donation = $7.50 + $3.75 = $11.25

Money needed for trip is not given so let it be x.

Now the least number of tickets that needs to be sold is given by x/11.25

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.
