Cost = fix cost + hourly cost - discount
Cost = 4* [5 + 4x - 4x(20/100)] = 4*[5 + 4x - 0.8x] = 4*[5 + 3.2x] = 20 + 12.8x
Answer: option B) 12.8x + 20

-6 because I did it on my calculator
Given the table
C : 1, 2, 3, 4, 5
F(C) : 4, 6, 8, 10, 12
Usually, the independent variable is represented by the x-value while the dependent variable (or the function) is represented by the y-value.
Thus the points represented by the table are:
(1, 4), (2, 6), (3, 8), (4, 10) and (5, 15).
