The sixth grade band students are selling magazines to raise money for new instruments. As a reward for
selling, the students earn points to spend on prizes. Each student gets 25 points to start with, and then
they earn an additional 5 points for each magazine they sell. One student sold enough magazines to earn
100 points total. Use your expression from the previous question to determine how many points the
student will have left after spending 64 points on prizes.
