Tavon has a gift card for $115 that loses $2.50 for each 30-day period it is not used. He has another gift card for $95 that loses $2 for each 30-day period it is not used.

The question is incomplete:

Tavon has a gift card for $115 that loses $2.50 for each 30-day period it is not used. He has another gift card for $95 that loses $2 for each 30-day period it is not used.

Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal.

115-2.5x=95-2x

The value of the gift cards will be equal after 40 30-day periods.

Step-by-step explanation:

From the information given, you can write the following equation:

115-2.5x=95-2x, where x is the number of 30-day periods the gift card is not used.

Now, you can solve for x:

115-95=-2x+2.5x

20=0.5x

x=20/0.5

x=40

According to this, the answer is that the value of the gift cards will be equal after 40 30-day periods.

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.
