Math problems of the week: traditional algebra vs. Common Core-inspired algebra

III. Extra Credit:

1. Compare the ratios of math to language arts challenge in each problem.

2. The Common Core does not require that students solve systems of equations in more than two equations and two variables. Is this a problem?
