Money and Powers of 10

Charles is a cashier. When he was cashing out one day, he noticed something strange. All of the money in his cash register was either pennies, dimes, $1 bills, $10 bills, or $100 bills! He also noticed there was the exact same number of each. This happened 3 days in a row.

• 1 Complete the table below. Write equations for Day 2 and Day 3. Then find the products. As you work, think about what patterns you notice.

  	Day 1: 6 of each	Day 2: 18 of each	Day 3: 125 of each
  Bills or Coins	Equation and Product	Equation and Product	Equation and Product
  $100 bills	6 × 100 =	18 × 100 =
  $10 bills	6 × 10 =
  $1 bills	6 × 1 =
  Dimes	6 × 0.1 =
  Pennies	6 × 0.01 =

• 2 Look at the products in the table. What pattern(s) do you notice?
