A population of fruit flies is increasing at a rate of 22.5%. If the population had an original size of 10 flies
matrenka [14]

Answer:

Original size of population containing fruit files = 10 files

Rate at which population of fruit file is increasing = 22.5%

New population of fruit files having initial population of 10 files and increase rate of 22.5% is given by =

                                              10 + 22.5 × \frac{10}{100}

                                         = 10 + 22.5 × \frac{1}{10}

                                         = 10+ 2.25

                                           = 12.25 files
