Mattea was asked to find the measure of an interior angle of a regular octagon. Mattea’s work is shown below.

Steps
Mattea’s Work
Step 1
(n minus 2) 180 degrees = (9 minus 2) 180 degrees
Step 2
7 (180 degrees) = 1260 degrees
Step 3
1260 degrees divided by 8 = 157.5 degrees

Where, if at all, did Mattea first make a mistake finding the measure of an interior angle?
step 1
step 2
step 3
Mattea did not make a mistake.

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
