the sales tax rate is 9.8%. if kari buys a fountain priced at $474, how much tax will she pay? round your…

Explanation:

Step1: Convert percentage to decimal

To use the sales - tax rate in a calculation, we convert 9.8% to a decimal. We do this by dividing 9.8 by 100, so 9.8% = 0.098.

Step2: Calculate the tax amount

The tax amount is found by multiplying the price of the fountain by the sales - tax rate. The price of the fountain is $474 and the sales - tax rate is 0.098. So the tax amount $T$ is $T=474\times0.098$. $474\times0.098 = 46.452$.

Step3: Round to the nearest cent

Rounding 46.452 to the nearest cent (hundredth), we get $46.45$.

Answer:

$46.45$
