Step 1: Our output value is 50.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$50=100\%$.

Step 4: Similarly, $x=30\%$.

Step 5: This results in a pair of simple equations:

$50=100\%(1)$.

$x=30\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have

$\frac{50}{x}=\frac{100\%}{30\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{50}=\frac{30}{100}$

$\Rightarrow x=15$

Therefore, $30\%$ of $50$ is $15$

<h2>Answer: \boxed{21}</h2><h2 /><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2>

When you multiply two negatives (-, -,), you are gonna get a positive(+)

<em>[Like making a cross out of two lines].</em>

-3(-7) = +3(+7)

<h2>Since 3(7) normally <u>equals 21</u>, that would be the answer for this case.</h2>

What would a 44% decrease of 13 be?
TEA [102]

Answer:

13

Step-by-step explanation:

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

44% = 44/100 = 44 ÷ 100 = 0.44.

100% = 100/100 = 100 ÷ 100 = 1.

Decrease number by 44% of its value.

Percentage decrease = 44% × 13

New value = 13 - Percentage decrease
