Question

The cost of buying a small piece of land in a remote village since the year 1990 is represented by the following table . Which model c(t) the cost of the piece of land t years since 1990, best fits the data?

Answer 1

Answer:

C(t)=30+3.5t

Step-by-step explanation:

Time increases by 2, the average difference in the cost is approximately 7.

So if d is the common difference of the function modeling this relationship, then  2d≈72.

Therefore,  d≈ 7/2 = 3.5

Since the initial cost of the land is 30 thousand dollars, the function that best models its cost t years since 1990 is C(t)=30+3.5t

Answer 2

Answer:

C(t)=30+3.5t

Step-by-step explanation:

Yeah this is the answer
