If an item that originally cost $13 is increased to $19, what is the percentage of increase in the item?

Evgesh-ka [11]

Original cost (OC) = $13

New cost (NC) = $19

Percentage increase = $\frac{NC - OC}{OC} *100 = \frac{19 - 13}{13} * 100 = \frac{6}{13} * 100$

= 46.15 %

Pls help me with number

vredina [299]

Answer:

Total people = 240

Step-by-step explanation:

Let the total number of people by 'x'.

$\sf \text{Number of men =$ \dfrac{1}{4}*x$} \\$

$\sf \text{Number of women =$\dfrac{1}{3}x$}$

Number of children = 100

When we subtract the total number of men and women from the total people 'x', we get the number of children.

$\sf x - \left(\dfrac{1}{4}x+\dfrac{1}{3}x\right)= 100\\\\x - \left(\dfrac{1*3}{4*3}x+\dfrac{1*4}{3*4}x\right)=100\\\\$

$x- \dfrac{4+3}{12}x=100\\\\x - \dfrac{7}{12}x = 100\\\\ \dfrac{12}{12}x-\dfrac{7}{12}x = 100\\\\ \dfrac{5}{12}x=100\\$

$\sf x = 100*\dfrac{12}{5}\\$

x = 20 * 12

x = 240

<h3> Total number of people = 240</h3>
