Question

In nearby Nassau County, the sales tax rate is 8 5/8%. If you were to create an equation, graph and table for this tax rate, what would the points (0,0) and (1, 0.08625) represent. Explain their meaning in the context of this situation.

Answer 1

If you create its equation then y = .08625x

where

x is the amount to be taxed

y is the amount of sales tax

 

So, the points that you have mentioned about are given in this context (x,y). They will be represented like this:

If 0 is the amount to be taxed then sales tax must be 0. Basically, if you did not have any amount to begin with, you are not going to be taxed either.

 

If you purchased something for 1 or the amount that is going to be taxed by 1 will be multiplied by .08625 (the given sales tax rate in Nassau County) then 0.08625 will be taxed on the amount of 1.
