Question

A scientist mixes x liters of water into a container that had 10 liters of a mixture that is 12% salt and 88% water. The function f(x)=

Answer 1

110 liters of water

Explanation:

The computation of the number of liters of water added is shown below:

Let us assume the x be the liters of water

f(x) represents the salt percentage in the mixture

Given that

f(x) = 1.2 ÷ x + 10

f(x) = 1% = 1 ÷ 100 = 0.01

Now out the f(x) value in the above equation

0.01 = 1.2 ÷ x + 10

x + 10 = 1.2 ÷ 0.01

x + 10 = 120

x = 110 liters
