UNITED STATES PRODUCTION OF PHOTOGRAPHIC
EQUIPMENT AND SUPPLIES IN 1971
(a)Approximately what was the ratio of the value of sensitized goods to the value of still-picture equipment produced in 1971 in the United States?
(b)If the value of office copiers produced in 1971 was 30 percent greater than the corresponding value in 1970, what was the value of office copiers produced in 1970?
选项
答案
4 to 1
$765 million
解析
(a)The ratio of the value of sensitized goods to the value of still-picture equipment is equal to the ratio of the corresponding percents shown because the percents have the same base, which is the total value. Therefore, the ratio is 47 to 12, or approximately 4 to 1.
(b)The value of office copiers produced in 1971 was 0.25 times $3,980 million, or $995 million. Therefore, if the corresponding value in 1970 was x million dollars, then 1.3x= 995 million. Solving for x yields x =
≈765, so the value of office copiers produced in 1970 was approximately $765 million.
