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

The price of an airline ticket was $320 amd it is now 420$ what is the percent increase the price of the ticket
enyata [817]

Answer:

 31.25 percent increase

Step-by-step explanation:

To find the percent increase, we take

percent increase = (new - original)/new * 100 percent

                            = (420-320)/320 * 100 percent

                              100/320 * 100 percent

                              .3125 * 100 percent

                               31.25 percent increase
