Question

Gabe Amodeo, a nuclear physicist needs 60 liters of a 40% acid solution. He currently has a 20% solution and a 50% solution. How many liters of each class does he need to make the needed 60 liters of 40% acid solution.



please help someone

Answer 1

@spimentel Any idea?

Answer 2

lol no,

Answer 3

u?

Answer 4

The goal is 60 L of 40%, so arrange it in the right side of the equation!
Does it make some sense?

Answer 5

no. :( can you show me step by step or solve the problem that way i can learn how to get the answer>

Answer 6

I'm explaining step by step!

Answer 7

I DONT KNOW HOW TO ARRANGE THE EQUATION

Answer 8

I'm not sure that I fully understand the problem.., sorry... :(
miss @ajprincess may can help ...:D

Answer 9

OK THANK YOU.

Answer 10

= 60 * 40%
Done with the right side!

Answer 11

Can you make a wild guess what to put on the LEFT side?

Answer 12

60 LITERS *20%

Answer 13

WRONG, because we already used 60L for the RIGHT side!

Answer 14

What numbers left to arrange in the LEFT side?

Answer 15

20 AND 50

Answer 16

Yes, but we don't know the volume => 50x and 20 ( 60 - x)

Answer 17

Can you write the complete equation now?

Answer 18

(50-40):(40-20)=60

Answer 19

Mixture means adding: 50x and 20 ( 60 - x)
50x + 20 ( 60 - x) = 40* 60
5x + 2 ( 60 - x) = 240
Now solve it!

Answer 20

I GOT 40>

Answer 21

It means 40L of 50% and...

Answer 22

20L OF THE REMAINDING SOLUTION

Answer 23

Yes, 20 L of 20%

Answer 24

:) GOT IT. THANK SOOOOOOOOO MUCH, FOR BEING SOOOO PAT WITH ME

Answer 25

Crystal clear :)

Answer 26

YES LOL

Answer 27

Practice makes perfect, then!

Answer 28
