• I am thinking of a number with 5 digits. • The tens place has a value of 70.
• There are 9 ten thousands in this number
• The ones place has 3 ones.
• It would take 80 tens to model the value in the hundreds place.
• The value of the digit in the thousands place is four thousand.
What is my number?
