Answer:

Step-by-step explanation:
see the attached figure to better understand the problem
Let
c -----> the cost of some taxi journeys
n ----> the number of miles
we know that
The graph is a line
The equation of a line in slope intercept form is

where
m is the slope
b is the c-intercept (value of c when the value of n is equal to zero)
Observing the graph we have the points
(0,2.5), (5,5.5)
<em>Find the slope</em>
The formula to calculate the slope between two points is equal to
substitute the values
we have
-----> because the point (0,2.5) is the c-intercept
substitute in the equation of slope-intercept form

Answer:
24
Step-by-step explanation:
Area of the trapezium = 1/2(18 + 6) x 12
Area of the trapezium = 144 in²
------------------------------------------------
Answer: Area = 144 in²
------------------------------------------------
189.9 miles= 305.614
