D)

The cost is a direct variation of the days by a factor of 8. 

Answer:

Correct option is:

c=8d

Step-by-step explanation:

Days               Cost

2                       16=2×8

3                       24=3×8

5                       40=5×8

6                       48=6×8

As we can clearly observe from the table above that if d is the number of days then the cost c is written as:

c=8d

Hence, Correct option is:

c=8d
