If the hourly rate is r, then Hannah made 10x dollars and Zach made 9x dollars.
10x + 9x = 950
19x=950
x=50
That is their hourly rate
So, Zach made 9*50=450

Answer:

Zach earned $450.

Step-by-step explanation:

If $x is their hourly pay, then we have the equation:

10x + 9x = 950

19x = 950

x = 50.

So they each earned $50 per hour and Zach's pay was 9*50 = $450
