The tax rate is 6 %
Solution:
Given that, A man purchased a magazine at the airport for $ 2.89
The tax on the purchase was $ 0.18
To find: tax rate in percentage
From given,
Magazine price = 2.89
Tax amount = 0.18
Therefore, tax percent is given as:
Let "x" be the tax percent
x % of magazine price = tax amount
x % of 2.89 = 0.18
Solve the equation for "x"
[tex]x \% \times 2.89 = 0.18\\\\\frac{x}{100} \times 2.89 = 0.18\\\\2.89x = 0.18 \times 100\\\\2.89x = 18\\\\Divide\ both\ sides\ by\ 2.89\\\\x = 6.22 \approx 6[/tex]
Thus tax rate is 6 %
