if a new shirt costs $34.99 and the sales tax is $2.10, the sales tax rate is 2 percent. 4 percent. 6 percent. 8 percent.
Answer
Explanation:
Step1: Recall sales - tax rate formula
The formula for the sales - tax rate $r$ is $r=\frac{\text{Sales Tax}}{\text{Cost of Item}}\times100%$.
Step2: Substitute given values
We have the cost of the item $C = 34.99$ and the sales tax $T=2.10$. 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:
C. 6 percent
