Answer:

Let's say Samantha's earning is x, Mia's earning is y

So x - y = 250 and x + y = 2500

<=> x = 250 + y and x + y = 2500

<=> 250 + y + y = 2500

<=> 2y = 2250

<=> y = 2250 / 2 = 1125

So x = 250 + 1125 = 1375

Checking:

1375 - 1125 = 250 and 1375 + 1125 = 2500

So Samantha's earning is $1375 and Mia's earning is $1125
