if a new shirt costs $34.99 and the sales tax is $2.10, the sales tax rate is\n2 percent.\n4 percent.\n6 percent.\n8 percent.
Answer
Explanation:
Step1: Recall tax - rate formula
The formula for the sales - tax rate $r$ is $r=\frac{\text{Sales Tax}}{\text{Cost of Item}}\times100%$.
Step2: Substitute values
We are given that the cost of the item is $$34.99$ and the sales tax is $$2.10$. So, $r = \frac{2.10}{34.99}\times100%$.
Step3: Calculate the rate
$\frac{2.10}{34.99}\approx0.06$, and $0.06\times100% = 6%$.
Answer:
6 percent.
