Step-by-step explanation:
Federal funding for the national center for missing adults declined from 1.5 million in 2002 to 1 million in 2006. The amount by which it decreased is determined by subtracting the amount in 2006 from the amount in 2002. It becomes
1500000 - 1000000 = 500000.
The percent decrease in the federal funding from 2002 to 2006 will de determined by dividing the decrease by the amount in 2002 and multiplying by 100. It becomes
500000/1500000 × 100 = 33.33%
