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 !
