Answer:

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. %3D 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.

Answer:

Julie will get there first by 19 days.

Step-by-step explanation:

You have no question here. Leave a remark if I am wrong, but I think you want to know how many days it takes to reach 1000.

Givens

$12 every 4 days

$19 every 6 days

Solution

Mary

1000 / 12 = 83 1/3 periods that she has to contribute 12 dollars

83 1/3 * 4 = 333.3333 days to reach 1000 dollars.

Julie

1000 / 19 = 52 12/19

52 12/19 * 6 = 52.6316 * 6 = 316 days rounded.

Julie has the fewest number of days
