Question

a $380 television cost $411.35 after tax is added. what is the percentage of the tax? a 8.0% b 8.25% c 8.5% d 8.75% e 9.0%

Explanation:

Step1: Find the tax amount

Subtract the original price from the after - tax price. The original price of the television is $380, and the after - tax price is $411.35. So the tax amount $T = 411.35−380 = 31.35$.

Step2: Calculate the tax percentage

The formula for tax percentage $r$ is $r=\frac{T}{\text{Original Price}}\times100\%$. Substitute $T = 31.35$ and the original price = 380 into the formula. So $r=\frac{31.35}{380}\times100\%$. First, calculate $\frac{31.35}{380}=0.0825$, then multiply by 100% to get $r = 8.25\%$.

Answer:

B. 8.25%
