If you purchase an ipod that costs $339, how much sales tax will you pay if the rate is 8.375%?

Dominik [7]

The sales tax amount is $ 28.4

Solution:

Given that you purchase an ipod that costs $339

The tax rate is 8.375 %

To find: Sales tax amount

From given,

Cost price = $ 339

Tax rate = 8.375 %

Therefore, sales tax amount is 8.375 % of cost price

$Sales\ Tax\ Amount = 8.375 \% \text{ of } 339\\\\Sales\ Tax\ Amount = 8.375 \% \times 339\\\\Sales\ Tax\ Amount = \frac{8.375}{100} \times 339\\\\Simplify\ the\ above\ expression\\\\Sales\ Tax\ Amount = 0.08375 \times 339\\\\Sales\ Tax\ Amount = 28.39125 \approx 28.4$

Thus sales tax amount is $ 28.4
