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.
