Question 284330
100 Pounds of chemical cost       $ 97
1 Pound of chemical will cost        $ 97/100
2000 Pounds of chemical will cost    $ (97/100) * 2000 =  $ 1940

btw, is the second question a real-life question or a made up one. 10,000 eur is not equal to 0.7615 USD, it is much more than that. One can still answer this if that is a made question. Do let me know.
