This week in Precalc 11, we learned how to solve my modeling problems. This is solving a word problem by determining the relationships between the variables presented in the problem.

To solve these types of problems, you have to remember that quadratics work for 2 missing variables. Then, determine the variables in the problem and then any other information that the question may be asking. The questions will usually be using terminology like Sum, Product, Greatest, Least, etc. Next, identify the relationship between these variables. This will allow you to solve the rest of the problem. After the relationships are established, you can then solve to produce the answer you’re looking for.
