Answer:
If the 20% discount is by the hour then the answer would be $11.70 I think.
0.25x78= 19.50
19.50x0.20(20%)= 3.90
19.50-3.90-3.90= 11.70

Equation: y = -x + 9
3 blocks away: 6 visits
Step-by-step explanation:
Calculate slope from point (1, 8) to point (3, 7) on the line.
The y-intercept is where the line meets the y-axis.
The equation took a bit of guessing, but the -x is the y = x line, but reversed. 9 is the y-intercept.
Check the point on the line where x = 3.
