Your friend’s math test contained 42 questions, some of which were worth two points while the rest were worth three points. Your friend tells you that a perfect score is 100 points, but she cannot remember how many of each type (2 point or 3 point) were on the test.
Help your friend out: how many of each type were on the test?
