PLEASE HELP ME WUICKLY IF YOU FIND THE ANSWER PLEASE EXPLAIN WHY Which statement about the mean absolute deviation (MAD) of a data set is not true?

A. The MAD is the average distance of data values from the mean.

B. If a data set has a greater MAD than another data set, then it
varies more than the other
data set.

c. If a data set has a lower MAD than another data set, then it also
has a lower mean than the other data set.

D. The MAD is a way to measure the variation of a data set.

12n + 25

Step-by-step explanation:

Let x represent the amount that the school pays for ordering one shirt.

This includes the $25 flat-rate shipping cost. This means that if n shirts are ordered, the total cost including shipping would be expressed as

nx + 25

The school pays $1825 for 150 shirts. The expression would be

150x + 25 = 1825

150x = 1825 - 25

150x = 1800

x = 1800/150

x = $12

Therefore, the equation that models the total cost as a function of the number of n T-shirts ordered is

12n + 25
