Maria created a graph of B(t), the temperature over time. For the interval between t = 3 and t = 7, the average rate of change in her graph of B(t) is 8. Which statement must be true?
A. The temperature was 8 degrees higher when t = 7 than when t = 3.
B. The temperature was 8 times higher when t = 7 than when t = 3.
C. The temperature was 32 degrees higher when t = 7 than when t = 3.
D. The temperature was 2 degrees higher when t = 7 than when t = 3.

Given:
t = 3 ; t =7
Average rate of change in her graph is 8.

7-3 = 4
8 x 4 = 32

C. The temperature was 32 degrees higher when t = 7 than when t = 3.

The true statement would be; C. The temperature was 32 degrees higher when t = 7 than when t = 3.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Maria created a graph of B(t), the temperature over time.

For the interval between t = 3 and t = 7,

the average rate of change in her graph of B(t) is 8.

We can see that

The difference between the two temperatures gives

7-3 = 4

8 x 4 = 32

The true statement would be; C. The temperature was 32 degrees higher when t = 7 than when t = 3.
