Answer:

Must add 100 milliliters of water

Step-by-step explanation:

Let

x ----> milliliters of water to add

we know that

<em>Originally</em>

The milliliters of lemon concentrate is equal to the 10% of 100 mL

so

0.10(100)=10\ mL

<em>Now</em>

The balance of lemon concentrate is equal to 5%

The milliliters of lemon concentrate is the same

so

0.05(100+x)=10

solve for x

5+0.05x=10

x=100\ mL

therefore

Must add 100 milliliters of water
