15. In 1980 the government spent $12 billion for direct cash payments to single parents with dependent children. If this was 2,000 percent of the amount spent in 1956, what was the amount spent in 1956? (1 billion = 1,000,000,000) (A)$6 million
(B) $24 million (C)$60 million
(D) $240 million (E)$600 million

not too sure how to attack this problem. do we use scientific notation?

So if amount spend in 1956 = x, then 20x = 12 buillion
x = 0.6 billion = 600 million

E. 600 Million

1956 = x
So 1980 = x*2000/100 = 12 billion
Solve for x
x=3/5 billion
=0.6 billion
=600 million
600,000,000
(1 million = 6 zeroes, 1 billion = 9 zeroes)

$12 billion = 12*10^9 X=amount spent in 1956 then 12*10^9=(2000/100)*X 12*10^9=20*X we can write 10^9 as 5*20*10^7 so 12*5*20*10^7=20*X (cancel out 20) X=60*10^7 = 600,000,000 = 600 million so Answer is E CEO Joined: 21 Jan 2007 Posts: 2764 Location: New York City Followers: 9 Kudos [?]: 354 [0], given: 4 Re: ps #15 [#permalink] 16 Jun 2007, 20:53 bmwhype2 wrote: 15.

X = (12 * 10^9 * 100)/2000

==> X = 6 * 10^8 ==> 600* 10^6

==> \$600 million

easy proportion
12 billion ---------------- 2 000 %
x ------------------------- 100%
x=12 billion*100/2000 = 600 million
