Question

What equation models the data in the table if d = number of days and c = cost?

Days Cost

2 44

3 66

5 110

6 132

Answer 1

22d

Explanation:

Answer 2

You can see that 44/2 = 22

66/3 = 22

110/5 = 22

132/6 = 22

Then, the relation between C and d is a constant.

C/ d = 22

And you can model C as:

C = 22d.

This model tells that the cost equals 22 times the days.
