Microsoft has a special version of its windows operating system that it sells at a low price in countries where cheap pirated software is widespread. the cost of producing another copy of this software is the same as the cost of producing another copy of the regular windows product. selling this "special edition" software at a low price in certain countries is very similar to what economists call:
a) welfare loss.
b) natural monopoly.
c) a price taker.
d) price discrimination.

Write a function balancechemical to balance chemical reactions by solving a linear set of equations. the inputs arguments are: reagents: symbols of reagents in string row array products: symbols of products in string row array elements: elements in the reaction in string row array elcmpreag: elemental composition of reactants in two dimensional numeric array elcmpprdcts: elemental composition of prducts in two dimensional numeric array hint: the first part of the problem is setting up the set of linear equations that should be solve. the second part of the problem is to find the integers from the solution. one way to do this is to mulitiply the rational basis for the nullspace by increasing larger integers until both the left-and right-side integers exist. for example, for the reaction that involves reacting with to produce and : reagents=["ch4", "o2"]; products =["co2", "h2o"]; elements =["c","h", "o"] elcmpreag=[1,4,0;
