One month, Ruby worked 8 hours more than Isaac, and Svetlana worked 4 times as many hours as Ruby. Together they worked 148 hours. Find the number of hours each person worked.
Isaac hrs = x
ruby hours = x+8
Svetana = 4(x+8) All of this is given in the Q
added together all of these hours = 148
x + x+ 8 + 4 (x+8) = 148
6x +40 = 148
6x = 108
x = 18 = Isaac hours
Ruby = x+ 8 = 26
Svetlana = 4(x+8) = 104 hours
