If the original quantity is 15 and the new quantity is 24 what is the percent increase

Assuming the 15 and 24 is dollars,  

To find Markup % use the following equation

Markup%=Markup/Cost*100

and  

Markup=Selling Price-Cost

Markup=24-15= $9

The Markup is now $9

Now, Markup%= 9/15

=0.6*100

=60

Thus, the markup was 60%.

60 percent increase❤️

Step-by-step explanation:

I'm going to try to explain it to u easiest way possible ❤️

if 15=100 percent,

then 24=x percent.

we need to find x value,

lets use proportion:

(Multiply the two opposite corners with numbers; then divide by the other number, which is opposite corner of x, in our case 15)

x=(24×100)/15=160 percent

now lets subtract 100 percent from 160

160-100=60 percent.

so it increased with 60 percent.

or other way u could just subtract

15 from 24 first and u would get 9 dolars increase and would calculate for 9)

then u would do the same things as we did above.

I'll do it too for u:

if 15=100 percent

then 9=x

x=(9×100)/15=60 percent

hope i helped you❤️

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
