if a new shirt costs $34.99 and the sales tax is $2.10, the sales tax rate is\no 2 percent.\no 4 percent.\no 6 percent.\no 8 percent.
Answer
Explanation:
Step1: Recall sales - tax rate formula
The sales - tax rate formula is $\text{Sales - tax rate}=\frac{\text{Sales tax}}{\text{Cost of item}}\times100%$.
Step2: Substitute given values
We are given that the cost of the item is $$34.99$ and the sales tax is $$2.10$. So, $\text{Sales - tax rate}=\frac{2.10}{34.99}\times100%$.
Step3: Calculate the rate
$\frac{2.10}{34.99}\times100%\approx\frac{2.10}{35}\times100%$. Since $\frac{2.10}{35}=0.06$, then $0.06\times100% = 6%$.
Answer:
6 percent.
