What equation models the data in the table if d = number of days and c = cost? days cost 2 6 3 9 5 15 6 18

The equation models the data is given by

Step-by-step explanation:

Since we have given that

Days  Cost

2          6

3          9

5         15

6         18

Let the number of days be 'd'.

Let the cost be 'c'.

So, we can see that there is direct variation between d and c :

Hence, the equation models the data is given by
