Question

c. 6% sales tax on a $20 shirt

Explanation:

Step1: Convert percentage to decimal

To find the sales tax, we first convert the percentage to a decimal. 6% is equal to $0.06$ (since $6\%=\frac{6}{100} = 0.06$).

Step2: Calculate the sales tax

We multiply the price of the shirt by the decimal form of the tax rate. The price of the shirt is $520$, so the sales tax is $520\times0.06$.
Calculating that: $520\times0.06 = 31.2$.

Answer:

The sales tax is $\$31.2$.
