Zoie Beasley · Answer 1

FIrst, you can make an equation to solve this problem

870/x=30/100 Cross multiply and then divide

870 times 100=87000

Then do 87000 divided by 30

The answer is 2900 milligrams of salt

Steve Hodge · Answer 2

870 milligrams = 30% of recommended.

870 = 30% of x

30% of x = 870

0.30x = 870

x = 870 / 0.3

x = 2900

Daily recommended is = 2900 milligrams.
