In the US House of Representatives, about 12.2% ofthe representatives are from the state of California. If there are 435 representatives, how many are not from California?
A.12.2
B.53
C.382
D.488
答案:C
解析:
Choice C is correct. Use the variable r to representthe number of representatives from California, set upan equation to determine how manyrepresentatives are from California.
(0.122)(435)=r, and so r=53.07
There are 53 representatives from California.
To find the number of representatives not from California, subtract the number ofrepresentatives from California from the total number of representatives.
435-53=382
Therefore, 382 of the representatives are not from California.
