Question

help please..A soil supplement that weighs 18 lb contains iron, potassium, and a mulch. There is fifteen times as much mulch as iron and twice as much potassium as iron. Find the amount of mulch in the soil supplement.

Answer 1

If x is the amount of iron, how much potassium is there? How much mulch is there?

Then you can set up an equation with x as the only variable. Give it a try and I'll give you a hand.

Answer 2

x + 15x+ 2x= 18 like that?

Answer 3

Yes.
