Problema Solution
A mixture contains n liters of liquid of fertilizer in 10 liters of water. Write an expression for the concentration of fertilizer in the mixture. Explain what each part of the expression represents. If we have 100 liters of this liquid, how much of it is water and how much of it is fertilizer
Answer provided by our tutors
let 'x' represent the concentration of fertilizer in the mixture
x = the n liters of fertilizer/the total amount of the mixture(water + fertilizer)
x = n/(10 + n)
100x percents is fertilizer.
100(1 - x) percents is water.
