Full solution

Q. One year, the population of a city was 156156,000000 . Several years later it was 177177,840840 . Find the percent increase.\newlineAnswer: _____% \%
  1. Calculate Population Increase: Calculate the actual increase in population.\newlinePopulation initially: 156,000156,000\newlinePopulation later: 177,840177,840\newlineIncrease in population: 177,840156,000177,840 - 156,000
  2. Subtract to Find Increase: Perform the subtraction to find the increase. 177,840156,000=21,840177,840 - 156,000 = 21,840 The population increased by 21,84021,840.
  3. Calculate Percent Increase: Calculate the percent increase based on the original population.\newlinePercent increase formula: (IncreaseOriginal Population)×100%(\frac{\text{Increase}}{\text{Original Population}}) \times 100\%\newlinePercent increase: (21,840156,000)×100%(\frac{21,840}{156,000}) \times 100\%
  4. Perform Division and Multiplication: Perform the division and multiplication to find the percent increase.\newline(21,840/156,000)×100%=0.14×100%(21,840/156,000) \times 100\% = 0.14 \times 100\%
  5. Convert Decimal to Percentage: Convert the decimal to a percentage.\newline0.14×100%=14%0.14 \times 100\% = 14\%\newlineThe percent increase in the population is 14%14\%.
