Answer: The equation models the data is given by

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 :

$(d)/(c)=(2)/(6)\\\\(d)/(c)=(1)/(3)\\\\c=3d$

Hence, the equation models the data is given by
