Iain has 200 pennies. He realizes that 30 of his pennies are older than he is. If he wishes to get rid of these pennies and then throw out 20% of his remaining pennies, how many will he have left?
Start with taking out the older pennies 200 pennies - 30 pennies = <<200-30=170>>170 pennies
Take the 170 pennies * .20 = <<170*.20=34>>34
170 pennies - 34 pennies = <<170-34=136>>136 pennies.

Iain'in 200 penisi var. Bozuk paralarından 30 tanesinin kendisinden daha yaşlı olduğunu fark eder. Bu bozuk paralardan kurtulmak isterse ve sonra kalan bozuk paralarının %20'sini atarsa, geriye kaç tane bozuk parası kalır?
Eski kuruşları çıkarmakla başlayın 200 peni - 30 peni = <<200-30=170>>170 peni
170 peni * .20 = <<170*.20=34>>34'ü alın
170 peni - 34 peni = <<170-34=136>>136 peni.
