There are six 18-wheeler trucks, 5 school buses, and 10 cars driving down the same road. Kasey says there are 84 wheels in total. Is she correct, why or why not? If not, where was her error.
No, Kasey is not correct. An 18-wheeler truck has 18 wheels, a school bus has 4 wheels and a car has 4 wheels. 18 times 6 is 108, 5 times 4 is 20 and 10 times 4 is 40. You add 108+20+40 and you get 168 wheels. Kasey did not multiply 6 by 18 for the 18-wheeler trucks so that is where her error was.
