Opal won $100.00 betting on a horse race.  She put half of her winnings into savings and bet the other half of her winnings.  This time, she made a 60% profit and again, put half of her earnings into savings.  How much did she put into her savings?
She won $100.00 and put half into savings so she put 100/2 = $<<100/2=50.00>>50.00 into savings
She won $100.00 and put $50.00 into savings so that leaves 100-50 = $<<100-50=50.00>>50.00 to bet
She bet $50.00 and made a 60% profit so her profit was 50*.60 = $30.00
The total wins in the second bet are 30+50 = $<<30+50=80>>80
She put half of her $80.00 earnings into savings so that's 80/2 = $<<80/2=40.00>>40.00 into savings
She put $50.00 into saving from her 1st bet and $40.00 from her second so she has saved 50+40 = $<<50+40=90.00>>90.00
