Answer:
Range
Step-by-step explanation:
Range is found by subtracting the highest and lowest point in the dataset
Mode is the number that occurs most frequently in the set
Median is the central number in the dataset when arranged from lowest to highest
Mean is the sum of all the numbers in the dataset divided by how many numbers there are.
For example, take this list of numbers: 10, 10, 20, 40, 70.
The mean (also known as average) is found by: 10 + 10 + 20 + 40 + 70 / 5 = 30.
The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number: 20.
If the school spent $1,137.50 and wants to make a $1500 profit, then they need to make $2637.50 to earn back what they spent and make a profit. So, if you divide $2637.50 by 350, the number of books they purchased, you get the amount each book would have to cost to make this much money. The lowest price they could sell them for is $7.54.
