Why would a good have elastic demand? inelastic demand?

Many factors can influence if a good has an elastic or inelastic demand such as price. Let's use price as an example. Let's say that I am selling a good X at 10 dollars and in a given week I sell 200 items of the good X. If on the following weeks I test a higher price or even a lower price and the demand keeps the same we can say that the product could be inelastic.

Amath expression is a collection of one or more terms, which are separated by the signs ( + , - , x , / ).example :   8+b8+b  or  a−3a−3in algebra, an equation is a mathematical statement with two expressions where, each expression is separated by an equal (=) sign. variables can be present on both the sides of the equality (=) sign and we use letters to denote such variables.example 1:   x=4+2x=4+2  , [here, we can observe that the variable is present only on one side of the equation].example 2:   2x+3=x+42x+3=x+4  , [here, we can observe that the variables are present on both side of the equation].
