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. if p represents the number of points that the student already spent on prizes, write an expression to represent the total number of points the student has left. show me all works

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

answer: a and b
