Mary and julie both have a goal of raising $1000 for charity. mary raises $12 every 4 days. julie raises $19 every 6 days.
mary would have a rise of 12 and a run of 4, making her slope, or rate of change, $3 a day. julie would have a rise of 19 and a slope of 6, making her slope, or rate of change, $3.17 a day. since julie is raising money at a faster rate, she would get to the goal of $1000 first.

Mary would have a rise of 12 and a run of 4, making her slope, or rate of change, $3 a day.

Julie would have a rise of 19 and a slope of 6, making her slope, or rate of change, $3.17 a day.

Since Julie is raising money at a faster rate, she would get to the goal of $1000 first.

Step-by-step explanation:

Mary is raising $12 every 4day and Julie is raising $19 every 6 days.The money raised by Mary and Julie if plotted on a graph will be a linear equation.

The rise is the change in y coordinate and run is change is x coordinate .For Mary Rise is $12 and run is 4 So slope = Rise ÷Run = 12÷4= 3.

For Julie the rise is $19 and run is $19 .Slope = Rise ÷Run =19÷6=3.166=3.17

As rate of change for Julie is more so  Julie will get the goal of raising $1000 first.
