Answer
Explanation:
Step1: Convert percentage to decimal
To find the tax amount, we first convert the tax rate from a percentage to a decimal. The tax rate is (6%), and (6%=\frac{6}{100} = 0.06).
Step2: Calculate the tax amount
We know that the tax amount (T) is calculated by multiplying the cost of the item (C) by the tax rate (r). Here, (C = 30) and (r=0.06). So, (T = C\times r=30\times0.06).
[ \begin{align*} 30\times0.06&=(3\times10)\times\frac{6}{100}\ &=3\times\frac{6}{10}\ &=\frac{18}{10}\ & = 1.8 \end{align*} ]
Answer:
The amount of tax is (1.8) dollars.
