The senior counselor is making a histogram of the yearly cost of tuition of 20 colleges. tuition ranges from $5,000 to $51,000 a year. what would be best to count by, on the tuition axis? a) 1,000s b) 5,000s c) 10,000s d) 15,000s

It would be better to count by 5,000s on the tuition axis. This is because the range has a minimum of 5,000 and maximum of 51,000 which can be divided by 5. Changes in amount between each multiple of 5,000 can easily be understood. 

In the histogram, the x-axis will be the names of the school and the y-axis will be its corresponding tuition for the year.

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
