The correct answer is B) the mean will decrease and the median will stay the same.

Step-by-step explanation:

This is true because the mean is the average, which is all of the values added together and then divided by the number of teachers. Reducing anyone's salary will reduce the mean.

The median stays the same since she was already the lowest (or tied for the lowest) paid in the group. Therefore, the middle term (the median) is unchanged.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.
