I'll mark your answer At a local high school, 2 Algebra teachers have different beliefs about how to grade students. Mr. Derivative thinks all students should start with 100 points for their assignments and lose 5 points for every assignment that is not complete. Mr. Logarithm thinks that every student has to earn their points by starting with nothing and earning 15 points per assignment that is turned in.

-Write equations representing the amount of points earned in each teacher's class.
