Loudoun math tournament


Suppose that two middle schools and an elementary school hosted 600 students who were competing in a math tournament on five-member teams. One middle school hosted 12 fewer teams than did the other two schools. How many students competed at the elementary school?

That problem would be a breeze for many of the students who took part in the second annual Loudoun County Regional Math Tournament on March 7.
