Question

Aaron's hourly rate is $8 more than Rachel's if both of them work for 2 hours and received a total of $124 what is Rachel's hourly pay

Answer 1

a=r+8, ok?

2*a + 2*r = 124, right?

a+r = 62, a = r+8 ---> 2r + 8 = 62, r = 54/2 =27, so

Rachel's hourly rate is $27, Aaron is $35.

Check: 1 hour both $62, 2 hours 124!

Answer 2

Rachel's hourly pay is $27/hour and Aaron's hourly pay is $35/hour. 
27 x 2 = 54
35 x 2 = 70
70 + 54 = 124
