Answer:
Step-by-step explanation:
To write an equation, use the slope-intercept equation:
M is the slope and b is the y-intercept.
First, find the slope by using the slope formula for when you have two points:
Rise over run is the change in the y-axis over the change in the x-axis. Substitute values:
Simplify parentheses (two negatives make a positive) and simplify:
The slope, m, is 4. Insert this information into the equation:
Now, take one of the points and insert into the slope-intercept formula:
Solve for b, the y-intercept. Simplify multiplication:
Add 20 to both sides and simplify:
The y-intercept, b, is 20. Insert this value into the equation:
Done.
Answer:
<em>$4.84</em>

Step-by-step explanation:
Given that
For delivery within mi, charges = $1.25
For delivery within mi -
mi, charges = $1.70
For delivery within mi - 2 mi, charges = $2.15
and
so on.
i.e.
For delivery within 2 mi - 2 mi, charges = $2.60
For delivery within 2 mi - 2
mi, charges = $3.05
For delivery within 2 mi - 2
mi, charges = $3.50
For delivery within 2 mi - 3 mi, charges = $3.95
For delivery within 3 mi - 3 mi, charges = $4.40
So, every 0.25 mi or mi increase in distance, there is an increase of $0.45 in the charges.
It is given that there is increase of 10% in the rates.
i.e. for every 0.25 mi increase in distance, there is an increase of 0.45*1.10 = $0.495 in the charges.
The distance of miles lies within the range 3 mi - 3
mi.
So actual charges after increase of 10%
