There was a fair at Brad's high school this weekend. It was open for 10 hours on Saturday and the ticket sales were recorded. The ticket sales for Saturday can be approximated by the equation y = 4.6x - 12.2. What was the approximate rate of change for the number of tickets sold?

10 tickets/hour

12.2 tickets/hour

7.6 tickets/hour

4.6 tickets/hour

The rate of change is 4.6 tickets/hour.

Step-by-step explanation:

The equation that represents the ticket sales is the equation of a line:

y = 4.6*x - 12.2

The equation of any given line can be writen by the following formula:

y = m*x + b

Where "m" is the slope of the line, or the rate of change, while b is the value for "y" when "x" is zero. Therefore in this case the rate of change is the number multiplying "x", so 4.6 tickets/hour.

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
