One month, Ruby worked 6 hours more than Isaac. and Svetlana worked 4 times as many hours as Ruby . Together they workdd 126 hours. Find the number of hours each person worked

Answer 1

Let h be the number of hours Isaac worked.

Ruby worked 6 more hours than Isaac, or h + 6

Svetlana worked 4 times as many as Ruby or 4(h+6)

The total hours = 126

or

h + (h+6) + 4(h+6) = 126

Solving for h gives you

h + h + 6 + 4h + 24 = 126

6h + 30 = 126

6h = 96

h = 16 hours so Isaac worked 16 hours, which means Ruby worked 22 hours and Svetlana worked 88 hours
