Let's start by finding out how much Peter earns per month. If Donald earns S33,360 per month, which is 25% more than Peter's salary, then Peter's salary can be found by subtracting 25% of his salary from Donald's salary.
Let P = Peter's monthly salary
(1 - 25%)P = S33,360
0.75P = S33,360
P = S33,360 / 0.75
P = S44,480
Now, let's find out how much Teresa earns per month. If Peter earns S44,480 per month, which is 25% less than Teresa's salary, then Teresa's salary can be found by adding 25% of Peter's salary to Peter's salary.
Let T = Teresa's monthly salary
(1 + 25%)T = S44,480
1.25T = S44,480
T = S44,480 / 1.25
T = S35,584
Therefore, the monthly salary of Teresa is S35,584.
The monthly salary of Donald is 25% higher than that of Peter while the monthly salary of Peter is 25% lower than that of Teresa. It is given that the monthly salary of Donald is S33 360. The monthly salary of Teresa is how much?
