HEY! HERE'S YOUR ANSWER

Step-by-step explanation:

This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour.

Table

Time in Hrs     Cost ($)

     0                  0

     2                  10

     4                  20

     6                  30

     8                  40

Cost = a (hrs) + b

C = aH + b

0 = 0 + b

b = 0

C = aH

10 = a2

=> a = 5

=> C = 5H

Cost Per hour = 5 $

This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour.
