Jim wants to go to college. He does not have enough money to attend a four-year university, so he plans to attend El Paso Community College until he saves enough money to transfer to a university. Jim has $2,800 saved, but El Paso Community College costs $8,900 a year. He received a $2,000 grant and wants to work to earn 50% of the remaining cost. How much money does he need to earn from his job?

$2050

let me know if this is wrong

Step-by-step explanation:

8900-2800=6100

6100-2000=4100

4100(.50)=2050

We can extract the points (3, 21) and (6, 12) from the graph.

First we are going to find the slope of the line passing through those points. To do it, we are using the slope formula:

where

is the slope of the line

are the coordinates of the first point

are the coordinates of the second point

Our first point is (3, 21) and our second point is (6, 12), so let's replace the values

Now, to find the equation of the line in point, slope, we are using the point-slope formula:

where

is the slope of the line

are the coordinates of the first point.

Since we have the slope, let's replace the values:

Next, to find the equation in slope-intercept form, we just need to solve our point-slope equation for :

Answer

Equation of the line in point-slope form:

Equation of the line in slope-intercept form:

The time that initially took Scoot  to deliver his packages is the time it took him to deliver the packages in his first day of work. In the hist day of word, zero days has passed since he begin working, so .

It initially took Scoot 30 minutes to deliver his packages.

Now, since the slope of our line is negative 3, Scott's delivery time decreases 3 minutes per day.

Answer

It initially took Scoot 30 minutes to deliver his packages.

Scott's delivery time decreases 3 minutes per day.
