standard_description: Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them). For example, the expressions y + y + y and 3y are equivalent because they name the same number regardless of which number y stands for.

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?
