Step-by-step explanation:
We need at least two points to write the equation of a straight line.
The recursive formula that Elijah wrote is:
When we substitute n=0, we get:
The points (0,30) and (1,37) lies on this line.
The equation of this line is of the form:
where b =30 is the y-intercept and m=7 is the slope.
We plug in these values to get:
Note that the slope of the line is equal to the common difference of the Arithmetic Sequence.
You could also use the two points to find the slope:
Answer:
School District pays $42 less to substitute teacher than Mr. Dietz.
Step-by-step explanation:
Given:
Salary of Mr. Dietz per year = $22570
Number of days in a year = 185 days.
Amount paid for Substitute teacher per day = $80
We need to find the Amount less paid to substitute teacher then Mr Dietz when Mr. Dietz takes a day off.
Solution:
First we will find the Amount paid for per day of Mr. Dietz.
Amount paid for per day of Mr. Dietz can be calculated by dividing Salary of Mr. Dietz per year with Number of days in a year.
framing in equation form we get;
Amount paid for per day of Mr. Dietz =
Now we will find Amount less paid to substitute teacher then Mr Dietz.
Amount less paid to substitute teacher then Mr Dietz can be calculated by subtracting the Amount paid for Substitute teacher per day from Amount paid for per day of Mr. Dietz.
framing in equation form we get;
Amount paid for Substitute teacher per day = $122 - $80 = $42
Hence School District pays $42 less to substitute teacher than Mr. Dietz.
