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.
Find the percent of increase in the newspaper’s circulation from 2000 to 2001 and from 2001 to 2002.
Which period had a higher percent of increase, 2000 to 2001, or 2001 to 2002?
3640/3250 = 1.12
4100/3640 = 1.1263
so it looks like a growth of 12% per year, but it was faster after 2001.
To find the percent of increase, you would need to calculate the difference in circulation between two periods and then divide that difference by the original circulation. Here's how you can calculate the percent of increase for each period:
1. From 2000 to 2001:
- Subtract the circulation in 2000 from the circulation in 2001: 3,640 - 3,250 = 390.
- Divide the difference by the circulation in 2000: 390 / 3,250 = 0.12.
- Multiply the result by 100 to get the percentage: 0.12 * 100 = 12%.
2. From 2001 to 2002:
- Subtract the circulation in 2001 from the circulation in 2002: 4,100 - 3,640 = 460.
- Divide the difference by the circulation in 2001: 460 / 3,640 = 0.126.
- Multiply the result by 100 to get the percentage: 0.126 * 100 = 12.6%.
To determine which period had a higher percent of increase, compare the percentages calculated. The percent of increase from 2001 to 2002 is higher (12.6%) compared to the percent of increase from 2000 to 2001 (12%). Therefore, the period with a higher percent of increase is 2001 to 2002.
To find the percent of increase, we need to calculate the difference in circulation between the two years and then divide it by the initial circulation. We can then multiply the result by 100 to get the percentage.
From 2000 to 2001:
Difference in circulation = 3,640 - 3,250 = 390
Percent of increase = (390 / 3,250) * 100 ≈ 12%
From 2001 to 2002:
Difference in circulation = 4,100 - 3,640 = 460
Percent of increase = (460 / 3,640) * 100 ≈ 12.6%
Comparing the two percentages, we can see that the percent of increase from 2001 to 2002 is higher (12.6%) compared to the percent of increase from 2000 to 2001 (12%).
