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❤️
