Question

a car dealership owner created a data table to see how many new and used cars were sold over several months.

month	new	used
august	45	32
september	20	44
october	27	39
november	71	12
december	48	87

what is the range for the number of cars, new and used, that were sold from july to december?

Explanation:

Step1: Calculate total cars per month

July: \(37 + 63=100\)
August: \(45 + 32 = 77\)
September: \(20+44 = 64\)
October: \(27+39 = 66\)
November: \(71+12 = 83\)
December: \(48+87 = 135\)

Step2: Find maximum and minimum values

The total - car - count values are \(100,77,64,66,83,135\).
The maximum value \(M = 135\), the minimum value \(m=64\)

Step3: Calculate the range

The formula for range is \(R = M - m\).
So \(R=135 - 64=71\)

Answer:

\(71\)
