Answer 1

got any clue how you should solve this ?

Answer 2

like at least try to come up with something so I know what part you're not getting

Answer 3

First we set up the variables

Answer 4

I was going to prefer that he exhausts all his knowledge to come up with a solution

Answer 5

I actually would prefer if @Miracrown could help me come up with a basis for my attempts.

Answer 6

Shouldn't I do "0.07x + 0.04y = 500" to start off? @Miracrown

Answer 7

try to "attempt" so we know what knowledge is lacking

Answer 8

LOL- Ok, so Solution are mixed to make 500 milliliters
So X+Y =500. The other equation balances the amount of salt
we have .07 ml of salt in the first solution
.04ml of salt in the second solution
and .05 times 500 ml of salt in the mixture

Answer 9

You can easily solve the system now

Answer 10

you're missing this part 0.05 (500)

Answer 11

Alright, thank you.

Answer 12

it says 5% of 500 saline solution

Answer 13

yes and that equaled 25 which I multiplied by 100

Answer 14

so the answer is B, correct?
