States, of whom 22% lived in the West. Approximately, how many public school
students are projected to be living in the West in 2008?
【正确答案】
B
【答案解析】In 1988, 8,800,000 (22% of 40,000,000) students lived in the West. From 1988-1998 this figure increased by 27% —for simplicity use 25%: an additional 2,200,000 students; so the total was then 11,000,000. The projected increase from 1998-2008 is about 10%, so the number will grow by 1,100,000 to 12,100,000.

In 1979, how much more total tax would a resident of New York City who
had a taxable income of $36,500 pay, compared to a resident of New York City who
had a taxable income of $36,000?
【正确答案】
D
【答案解析】According to the tables, each additional dollar of taxable income over $25,000 was subject to a New York State tax of 14% and a New York City tax of 4.3%, for a total tax of 18.3%. Therefore, an additional $500 in taxable income would have incurred an additional tax of 0.183 × 500 = $91.50.
