Some time ago, a country's government obligated $30.5 billion in foreign economic assistance. The entire budget was $3.8 trillion. Estimate the percentage of the budget spent on foreign economic assistance by rounding the foreign economic assistance budget to $30 billion and the entire budget to $4 trillion. Calculate the percentage without using estimation and compare the two results. Round your answers in percentage form to two decimal places.

 

estimated value ____0.75__    %  Got this by doing 30,000,000,000 / 4,000,000,000,000 = 3 / 400 =0.0075 move two places equals 0.75%

 

exact value ___0.8%     Take 30,500,000,000/ 3,800,000,000,000 = 0.0080263158 move two decimal places and you get 0.8%

It asks for the percentage of the entire budget....sooo

the entire budget is 3.8 trill = 3,800,000,000,000  (rounded to 4 trill)       the foreign aid is rounded to 30000000000

 

  30,000,000,000/4,000,000,000,000   x 100% = .75 %

 

Can you do the other part without the rounding?

 

Sorry...I see you already did it ...BRAVO !
