A1A Quiz Review, End of Unit 5

A video walkthrough of the quiz review. Please note three minor mistakes, all of which have been corrected on the solution sheet in Classroom. #1 I got the slope of QR wrong. I stated that it was 1/3, but it was -1/3. This affects the perpendicular slope, which is actually 3, not -3. And this also affects the solution the point of concurrence in part b, which has been corrected in the solution guide. Also, I mistakenly put "y - 4" at the beginning of the equation of the perpendicular bisector of PR when it should have begun with "y - 2". #2 In part b, I made a math error, where I said the correct answer but wrote the wrong value. This onl affecfed the y-value of the poitnt of concurrence, which should be 5/3. (14/3 minus 3, NOT -14/3 minus 3) #3 In part b, I incorrectly wrote the price of 30 donuts for Eastside Donuts and Friendly Donuts. I plugged in 20 instead of 30. The correct cost at Eastside is o be $55, and as Friendly Donuts, i would be $65.
