Explanation:

The best way to find if each of the statmenet is true or false is to find the percentage in each case. To do this, follow this general formula: Total number / 100 (100 representes the total) x specific percentage. Now, let's apply this formula in each statement

A)

30 ÷ 100 = 0.3 x 15 = 4.5  (This statement is false)

B)

80 ÷ 100 = 0.8 x 25 = 20 (This statement is true)

C)

50 ÷ 100 = 0.5 x 30 = 15 (This statment is false)

D)

60 ÷ 100 = 0.6 x 30 = 18 (This statement is true)

E)

20 ÷ 100 = 0.2 x 40 = 8 (This statement is true)

$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
