Estimate what percent of decrease for population, Mathematics

Assignment Help:

The population of Hamden was 350,000 in 1990. By 2000, the population had decreased to 329,000. What percent of decrease is this?

First, ?nd out the number of residents who left Hamden through subtracting the new population from the old population; 350,000 - 329,000 = 21,000. The population decreased through 21,000. To ?nd what percent this is of the original population, divide 21,000 by the original population of 350,000; 21,000 ÷ 350,000 = 0.06; 0.06 is equivalent to 6%. If you chose d, you found the decrease in relation to the NEW population (2000) when the decrease must be in relation to the original population (1990).
