Answer:
C=4
Step-by-step explanation:
when solving these equations you have to get the letter by itself and in this case the 4 is being multiplied by the c so you have to do the opposite and divide the 4 from the c and divide 16 by 4 because what you do to one side of the equal sign you have to do to the other side.

The average is the sum of the observations divided by the count.
So the sum of the observations is the count times the average.
So the 9 teachers together make 9(1000)=$9000 per week. The 20 staff (9 teachers + 11 aps) makes 20(1275)=25500.
So the 11 aps must make 25500-9000=16500
So the mean ap salary is 16500/11 =$1500 per week
Clearly management is where it's at.
Check: (1500*11+1000*9)/20 = 1275 good
