standard_description: Work with 2 × 2 matrices as a transformations of the plane, and interpret the absolute value of the determinant in terms of area.

How many one-hundred dollar bills do you need to make \$2,000? \$20,000?
How many ten dollar bills do you need to make \$2,000? \$20,000?
How many dimes do you need to make \$0.20? \$2? \$20?
How many pennies do you need to make \$0.02? \$0.20? \$2?
Use the answers to the questions above to fill in the table:
{"table": [{"tbody": [{"tr": [{"td": [{"_value": "$A$"}, {"_value": "$B$"}, {"_value": "$A\\div B$"}]}, {"td": [{"_value": "2"}, {"_value": "0.01"}, {}]}, {"td": [{"_value": "20"}, {"_value": "0.1"}, {}]}, {"td": [{"_value": "200"}, {"_value": "1"}, {}]}, {"td": [{"_value": "2,000"}, {"_value": "10"}, {}]}, {"td": [{"_value": "20,000"}, {"_value": "100"}, {}]}]}]}]}
What changes (and how does it change) and what stays the same as you move from row to row down the table?
