In 2000, the circulation of a local newspaper was 3,250. In 2001, its circulation was 3,640. In 2002, the circulation was 4,100.

a. Find the percent of increase in the newspaper’s circulation from 2000 to 2001 and from 2001 to 2002.
b. Which period had a higher percent of increase, 2000 to 2001, or 2001 to 2002? (3 points)

2000 - 2001: 3640 - 3250 = 390
2001 - 2002: 4100 - 3640 = 460
390 divided by 3250 = 0.12
460 divided by 3640 = 0.1263736 = 1.26?

  4. The percent change is (new-original)/original.
    (3640 - 3250) / 3250 = 390 / 3250 = 39 / 325 = 3 / 25 = 12%
    (4100 - 3640) / 3640 = 460 / 3640 = 46 / 364 = 23 / 182 = 12.637...%

    The largest change came from 2001 to 2002.
