What would be the answer to this question?

87

Step-by-step explanation:

We are asked for the AVERAGE rate of change over two different periods.

We can begin by first figuring out the rate of change between the first and second day by subtracting the amount of parts from day 1 from the amount of parts from day 2.

132 - 66 = 66

We have our first value.

Next, We do the same thing with days 2 and 3. Subtract the amount of parts from day 2 from the amount of parts from day 3.

240 - 132 = 108

Now we are told to find the average. Finding averages is a 2-part process. Add the amounts together, and then dividing. We find averages by adding our values and then dividing by the amount of addends.

66 + 108 = 174

We have our sum of values, now we divide by the amount of addends we had; two.

174/2 = 87

Our final answer is an average of 87.
