Hope this helped :)you turn your percent into a decimal and multiply it buy your original price and you get how much money you're saving which is 18 dollars then you subtract it by your original price

Answer:

Step-by-step explanation:

when asked to decrease a number by a certain percentage, take the original number as 100%

here 90 is equivalent to 100%.

We subtract 20% from 100% to get 80% ( that's the new value)

On a trip, Alexander bought a ping-pong racket for $13. With the tax, he paid $14.04. What is the tax rate, in percent?

Fed [463]

Answer:

8% tax rate.

Step-by-step explanation:

$\frac{14.04}{13} =1.08$

The 8% (0.08) is the tax rate because the 100%, or 1.00, is the original price of the racket, which was $13.

Solve for www. Give an exact answer in simplified form. 53w+13 < 56w + 16

ki77a [65]

The solution will be: $w>-1$

Explanation

The given inequality is: $53w+13 < 56w + 16$

First we will subtract $56w$ from both sides. So.....

$53w+13-56w$

Now we will subtract 13 from both sides. So.....

$-3w$

Then we need to divide both sides by -3. As here we are dividing the inequality by a negative number, so we need to switch the inequality symbol. So, we will get.......

$\frac{-3w}{-3}>\frac{3}{-3}\\ \\ w>-1$

Thus, the solution will be: $w>-1$
