This new set is from the 1990 test.

Difficulty: Medium. It is, of course, a simple system but algebra II kids don't see that until you point it out. Pre-Calc should have no difficulty.

Difficulty: It Should Be Easy. See yesterday's mini-rant on fractions.

Standard instructions for this series: No calculator allowed. Express answers in reduced form. Rationalize denominators. Radicals must be reduced. All numbers are base ten unless otherwise specified. Do not approximate radicals or π. Leave such answers as 1025π or √39, for example. Source: UVM Math Contest 2013

answer 15, answer 16, Published 5/13.
