If a tutor charges $35 an hour and works for 286 minutes, what is the dollar amount she is owed?

Dollar Amount Owed = Hourly Rate * Number of Hours Worked

Convert Minutes worked to hours worked
Hours worked = Minutes Worked / 60
Hours worked = 286 minutes / 60 minutes per hour
Hours worked = 4.77

So now back to our main formula...
Dollar Amount Owed = Hourly Rate * Number of Hours Worked
Dollar Amount Owed = $35 * 4.77
Dollar Amount Owed = $166.95
