Answer:
$2.50
Step-by-step explanation:
The equation that describes Elizabeth's table can be found using the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (47.50 -27.50)/(3 -1)(x -1) +27.50
y = (20.00)/2(x -1) +27.50
y = 10x +17.50
Elizabeth's flat fee is $17.50. The difference between that and Mang's flat fee is ...
|17.50 -20.00| = |-2.50| = 2.50
The absolute value of the difference between the flat fees is $2.50.
