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

The answer will be D) 75

To find this it’s easiest to find how many animals there are per percent. So to find this you simply have to divide 30 (the number of cats) by 40 (the percent that makes up) to find the number of animals per percent.

30/40

.75

Then you multiply this by 100 to find how many animals there are total.

.75(100)
