Answer:
Let x represent the salary of the head and 3x represent the salary of the president. We can then write an equation to represent the given information:
x + 3x = 230,000
We can solve this equation by subtracting x from both sides and then dividing both sides by 4:
4x = 230,000 x = 57,500
Therefore, the salary of the head is $57,500 and the salary of the president is $172,500.
