Webassign Calculus 1 "Optimization Tricks"
AKA, how to "cheat" efficiently and gratuitously, particularly necessary if you're trying to do the whole thing in the free trial period. Red numbers in Webassign mean they change them to make it harder to cheat. They also haven't changed this mechanism for 10 years, so most if not all of the possibilities have already been answered. Google the text of the problem, and put quotes around the red variables to guarantee you get the results. This is a very efficient way to complete classically slow word problems (One red number is a guaranteed copy-paste solution, two is iffy, three is unlikely. But try anyway, since that could be free credit). If you don't, then it becomes a slower, but not particularly slow, replace-the-numbers problem. There's actually quite a few ways to create simple replace-the-numbers situations: If you hit "Watch it", you can get a solution to a similar problem. If you hit "Read it", and go to the examples section, on
