The formula P = m/v
where
p = density, m = mass, and V = volume, is used to calculate density. Solve this formula for m.
m=pv
m=p+V
m=p-v
V
m=-

step-by-step explanation:

$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

he answer is x=1x3 because x=1 to x=3
