Answer:
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❤️
