Biologists need to know roughly how many fish live in a certain lake, but they don't want to stress or otherwise harm the fish by draining or dragnetting the lake. Instead, they let down
small nets in a few different spots around the lake, catching, tagging, and releasing 96 fish. A
week later, after the tagged fish have had a chance to mix thoroughly with the general
population, the biologists come back and let down their nets again. They catch 72 fish, of
which 4 are tagged. Assuming that the catch is representative, how many fish live in the
lake?

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
