The five questions in this short quiz would all, I’m fairly sure, fit into the “Heart of Algebra” category that will be so heavily emphasized on the new SAT. Obviously, without even a full practice test released yet, it’s tough to know for sure if I’ve got the style right, but based on what I’ve seen, you’d better be able to cruise through these if you’re planning to take the SAT after January 2016.
(UPDATE: Try another set of questions in the style of the new SAT here.)

#4 why don’t we just multiply the cost per shirt of $13.80 (690/50) by 1.6? #5 can we just substitute zero for n and get h = k? Thanks for these! They were great fun!
Those are both solid alternate solutions. 🙂
How can C be a choice for 3? There is no z^3. I do not get this.
Oh jeez, that’s a big typo! Thanks for catching it—I’ll fix it right away.
