StephanieZ Posted March 30, 2010 Share Posted March 30, 2010 I'll play. 0.6 (50-x) + 0.9x = 32.4 x will give you # OT hrs .3x = 32.4 -30 x=8 Quote Link to comment Share on other sites More sharing options...
LuckyDuck103 Posted March 30, 2010 Author Share Posted March 30, 2010 I was totally stumped. (I got my answer by say all 50 hours had a base payment of 60c which is $30. Therefore she got paid $2.40 overtime at 30c/hour which gave me the same 8 hours.) Quote Link to comment Share on other sites More sharing options...
