This is going to be long but here i go

sally is paid a fixed amount of money to walk her neighbors dog every day after school. when she is paid each month, she puts aside $20 to spend and saves the remaining amount. write an expression that represents the amount sally will save in 6 months if she earns m dollars each month. if sally paid $65 each month, how much will she save in 6 months?

Expression : 6m - 120

Savings: $270

Step-by-step explanation:

Expression: 20 * 6 = 120

so you save $120 dollars every 6 months

Savings: 6(65)-120

^^substitute "m" for her pay or 65 in this case

390-120

^multiply 6 * 65

270

^subtract 390 - 120

$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
