what is Rachel's hourly rate of pay?

Question

Arjun's hourly rate of pay is $5 more than that of Rachel's. If both of them worked for 2 hours and received a total of $140, what is Rachel's hourly rate of pay?

Answer 1

Assuming each worked for 2 hours:

 

Let Rachael's rate be r, then Arjun's is r+5.

 

Therefore, Rachael's total pay is 2r and Arjun's is 2(r+5).

 

Add the total pay expressions and set equal to 140.  Can you take it from here?
