Answer: 6x+5y=28
Step-by-step explanation:
Looking at the first equation, we can tell that x stands for notebooks and y stand for pens. Since this talks about the total cost with the amount of products they bought, we can automatically eliminate the subtracting answer choices.
Now, we know that 6x+57=28 is the correct answer because Sonja bought 6 notebooks and 5 pens. This becomes 6x+5y.

Let the total number of teachers be x
Given:
The ratio of the number between male and female teachers is 5:9
Then the number of female teachers is 81
So 9/14*x=81
or, x=81/9*14
or, x=9*14
Therefore x=126
So the total number of teachers is 126.
Hence the number of male teachers =
5/14*126
=5*9
=45
Hence, the number of male teachers is 45.
