Maybe, the price went down $20 eight times?
The tens place will be where the zero is which the value would be 70 since the 7 is in the thousand place the value is 7,000
Your expected value is 36*2/6 + -36*4/6, which is equal to $-12.
Length of AB=Length of A'B' because they are corresponding sides.
913

<u />487 would be your total but your question is how many times we would have to regroup, so.
<u />
First, you would have to borrow from the 1 because 3 is smaller then 6. Second, you would have to borrow from the 9 because you can't take 2 from 0. So there you would have to regroup twice to work this problem.
Hope that helps you. :-)
