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

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.

B. 2 1/2 feet. multiply 2.5 inches by 12 to get thirty inches then divide by 12 to get 2.5 feet
