Ineed i don't really understand 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?

The formula for percentage change is:

(New number - Original number) / Original number × 100 = Percentage change

(3640-3250)/3250 x 100 =
(390)/3250 x 100 =
.12 x 100 = 12%

(4100-3640)/3640 x 100 =
(460)/3640 x 100 =
.1263736264 x 100 = ~ 12.6%

2001 to 2002 had a higher percent of increase.

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
