First, you need to find what 40% of 3000 is.
If 3000 is 100%, so we can write it down as 3000=100%
We know, that x is 40% of the output value, so we can write it down as x=40%
3000/x=100%/40%
3000/x=100/40
(3000/x)*x=(100/40)*x
- we multiply both sides of the equation by x
3000=2.5*x
- we divide both sides of the equation by (2.5) to get x
3000/2.5=x
1200=x
x=1200 this is how much they have raised so far.
now subtract 3000 from 1200 = 1800.
They need to raise $1800 to reach their goal.
Hope this helped! (:
