Miranda Frost · Answer 1

To get the previous population you would have to multiply 9,300 by 38% (.38) and then add it to 9,300, or you can also multiply it by 138% (1.38) and still get the same answer but this step is only a one step the first is a two step process

Origianl=100%

decresaed by 38%

100-38=62

62%=9300

find 100%

we can do ratio and proporition or something else

9300=62% of original

9300=0.62 times original

divide both sides by 0.62

14838.70967=original
