Question

How do you find the percent change given the original number is 50 and new number is 75?

Answer 1

First you see the original number, which, in this case, is 50
Then, you see the changed number, which, is 75
Then you see the difference,
`color(white)(^)`75
`color(white)(^)`-50
`color(white)(^)`=25
so the difference is of 25, and 25 of 50 =50% or `frac 50 100` so here the original number was 50, so, 50 was `100%` now it is `100% +50%`
So the number increased by `150%`
