IF A 30-DAY SUBSCRIPTION IS $499 PLUS 8% TAX, BUT IS BEING PRORATED FOR 7 DAYS, PLUS THERE IS A $10 OFF COUPON, WHAT'S THE FINAL
damaskus [11]

Answer:

$519.61

Step-by-step explanation:

We add the 8% tax 23 days of subscription since prorated for 7 days [30 - 7 = 23].

How much is 23 days subscription if 30 days is 499?

\frac{30}{499}=\frac{23}{x}\\30x=23*499\\30x=11,477\\x=382.57

We add 8% of this to 499:

0.08 * 382.57 =30.51

So cost is:

499 + 30.61 = 529.61

Now we have $10 off, so final cost would be:

529.61 - 10 = $519.61

Can someone please answer this
pashok25 [27]

Answer: -1

Step-by-step explanation:

If k is equal to negative one then we can input it into it for the exponent and solve.

10^{-3} * 10^{1} * 10^{-1}   If  multiplying exponents and they have the same base then you will just add the exponents and let the exponents stay the same.

The exponents are  -3,1, and -1 add them.

-3 + 1 - 1 = -3

The base is 10 so we will raise 10 to the negative 3rd power.

10^{-3}

Evan borrowed money from his mom. If he paid her back 9.60 which is 20% of the total he owns, then how much did he owe her to be
lyudmila [28]

Given:

Evan paid his mom back 9.60 which is 20% of the total he owns.

To find:

How much did he owe her to begin with.

Solution:

Let x be the amount Evan owns.

According to the question,

20% of x = 9.60

\dfrac{20}{100}x=9.60

\dfrac{1}{5}x=9.60

Multiply both sides by 5.

x=48

Therefore, Evan owns 48 from his mom.
