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

<em><u>Solution:</u></em>

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

BRAINLIEST AND FIVE STARS TO CORRECT ANSWER
Llana [10]
The answer is the first option, <-20, -42>.

We can find this by first finding what -2u would equal by multiplying <5, 6> by -2. This gives us <-10, -12>.

Then we need to find out what 5v is equal to, by multiplying <-2, -6> by 5 to get <-10, -30>.

Now that we know what -2u and 5v are, we can substitute them into the equation and get
<-10, -12> + <-10, -30>, which we can split up into -10 - 10 = -20, and -12 - 30 = -42, so your final answer is <-20, -42>.

I hope this helps!
