Answer

Explanation:

Step1: Convert percentage to decimal

To find the amount of tax, we need to convert 7 percent to a decimal. Percent means per - hundred, so 7 percent is $\frac{7}{100}=0.07$.

Step2: Calculate the tax amount

The tax amount is found by multiplying the cost of the television ($445) by the tax rate (0.07 or $\frac{7}{100}$). So the tax amount is $445\times0.07$ or $445\times\frac{7}{100}$.

Answer:

Tax = 445(0.07), Tax = 445(7/100)
