Elasticity of T in respects to X
Given the following example I need to find elasticity of t in respects to x.

T=100x/20+x+49

I'm stuck on it and don't know where to go with it.

1. your equation needs some parentheses to make it clear.

2. what is the definition of "elasticity" of T w/r to x ?

1) t=100x/(20+x)+49
2) and I don't understand this.

you're the one taking the course ... what does your text say about "elasticity" ?

It is elasticity in regards to the chain rule of the question above. I think it t is suppose to be price and x is quantity, because we've only talked about elasticity of demand in class thus far.
