D.$30.00 per person

Answer 1

Answer:

B. $15.00 per person

Step-by-step explanation:

Rate of change = change in total cost ÷ change in no of friends

Thus, we can use any two given pairs on the table.

Let's use, (2, $30.00) and (3, $45.00)

Rate of change = $\frac{45.00 - 30.00}{3 - 2}$

Rate of change = $\frac{15.00}{1}$

Rate of change = $15$

Therefore, the rate of change is $15.00 per person.

B. is the correct answer.
