Answer: B. c = 22d

I'm gonna go with c=22d

Step-by-step explanation: 22d

C = 22d is the correct answer because for every day the cost increases by 22 so two days mean the cost is equal to 22 (2)

...............................................................................................................................................

Answer:

The equation that models the data in the table is:

Step-by-step explanation:

The table that represent the days and cost is given by:

Days Cost

2 44

3 66

5 110

6 132

We see that the cost is a constant multiple of the number of days.

i.e. the equation is given by:

c=22d

i.e. the relationship is linear.

( Since, when d=2

we have: c=22×2=44

when d=3 we have:

c=22×3=66

and so on )

...............................................................................................................................................

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.
