(a)on july 15,2007 , the national debt of the united states of americawas a little more than 8.8 trillion dollars. at that time, the population of the united states was a little more than 300 million. approximately how much money would each of the 300 million people living in the united states have to give the government to pay off the national debt? assume every person pays an equal amount.
(b)
a rectangular garden with dimensions five meters by six meters has a sidewalk 1 meter wide allt e way around it. what is the total area of the graden and the sidewalk?
(a) Divide the national debt by the population
(b) The garden with surrounding sidewalk has rectangular dimensions of 7 x 8 meters. Compute the area.
(a) To find out how much money each person would have to give to pay off the national debt, we need to divide the national debt by the population of the United States.
National debt = $8.8 trillion
Population = 300 million
To convert trillion to billion, we multiply by 1,000.
National debt in billions = $8.8 trillion * 1,000 = $8,800 billion
Now we can calculate how much each person would have to give:
Amount per person = National debt in billions / Population
Amount per person = $8,800 billion / 300 million
To divide billion by million, we divide by 1,000.
Amount per person = $8,800 billion / 300 million * 1,000 = $\frac{8,800}{300} = $29.33 (approximately)
Therefore, approximately each person would have to give the government $29.33 to pay off the national debt if every person pays an equal amount.
(b) To find the total area of the garden and the sidewalk, we need to calculate the area of the garden and the sidewalk separately and then add them together.
The dimensions of the garden are 5 meters by 6 meters.
The dimensions of the garden with the sidewalk are 7 meters by 8 meters (adding 2 meters to each side of the garden).
Area of the garden = length x width = 5 meters x 6 meters = 30 square meters
Area of the garden with the sidewalk = length x width = 7 meters x 8 meters = 56 square meters
The total area of the garden and the sidewalk is the sum of the two areas:
Total area = Area of the garden + Area of the garden with the sidewalk
Total area = 30 square meters + 56 square meters = 86 square meters
Therefore, the total area of the garden and the sidewalk is 86 square meters.
