Cost of item:
10$. Sales tax: 0.46

50$ sales tax: 2.30

5$ sales tax: 0.23

What is the sales tax rate in Nevada?

Write an expression for the amount of sales tax charged, in dollars, on an item that costs c dollars.

Answer 1

hoped this helped

Explanation:

• 10$ x 0.46= 4.6

10$ + $4.20 = $14.20

• 50$ x 0.230= 11.50

50$ + $11.50= $61.50

• 5$ x 0.23 = 1.15

5$ + $1.15= 6.15$

Answer 2

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 $.
