2. True Story:
When you have money in a savings account, you sometimes get interest (2% or
3%) on your money. That’s the bank’s way of thanking you for investing your
money with them. The % interest produces money amounts that are long decimal
numbers.
A crooked investment banker decided to round everyone’s account balance
down (to the nearest penny), and to pocket the fractions of pennies for himself,
in a secret account. He did this once a month, thinking no one would notice.
a.
Circle the decimal numbers that go beyond the penny’s place, in each
amount in question 1. Add them up to determine how much money he
would make from the 6 cash amounts in question 1.
A: (3 marks)
