question: There are 9,300 pennies in a cup. What is the total dollar amount in a stack that contains two thirds of the pennies in the cup?
answer: A third of the pennies in a cup is 9,300/3 = <<9300/3=3100>>3,100.
  Number of pennies in the stack is 3,100*2 = <<3100*2=6200>>6,200.
  Total dollar amount in the stack is 6,200/100 = <<6200/100=62>>62.
