Answer:
$142,500
Explanation:
Let's say x is the salary of the department head.... so the salary of the president of the university can be described as 3x.
Then, we know the total of the two salaries is 190,000. We can express this as:
3x + x = 190,000
4x = 190,000
x = 47,500
x is for the department head. To get the president's salary, we have to multiply that by 3:
p = 3 (47,500) = 142,500
The salary of the president is then of $142,500.
