Answer:
Therefore the sales tax rate in Nevada is 4.6%.
For an item that costs c dollars, we have:
c$ ·4.6%=c·0.46 $.
Explanation:
From exercise we have that :
Cost of item:
10$. Sales tax: 0.46
50$ sales tax: 2.30
5$ sales tax: 0.23
We calculate the sales tax rate in Nevada, and we get
10$:100=0.46:x
10x=100· 0.46
10x=46
x=4.6%
Therefore the sales tax rate in Nevada is 4.6%.
The same can be done for the other two cases.
For an item that costs c dollars, we have:
c$ ·4.6%=c·0.46 $.
