Answer 4

Thanks but this was no help for me. :(

Answer 5

Do you want an example and how to solve for a variable?

Answer 6

Sure how about this. Its from my book P(x)=90(1+1.5x)/(1+0.5x)

Answer 7

That is a function, that is typically something to be graphed.
\(P(x)=\dfrac{90(1+1.5x)}{(1+0.5x)}=\dfrac{90+135x}{1+0.5x}\)
