Best ResponseYou've already chosen the best response.2this is like the tenth time i have seen this question, maybe i should make a template for it

Best ResponseYou've already chosen the best response.2first off it says "Write an equation in one variable " and your equation has two , so lets start again

Best ResponseYou've already chosen the best response.0Ok, other than that, am I on the right track?

Best ResponseYou've already chosen the best response.2secondly it has "find the total number of liters of apple juice and water in the jar. " which is stupid because you know the number of liters of water right?

Best ResponseYou've already chosen the best response.0Yea, 1 right? And there's 3 of juice?

Best ResponseYou've already chosen the best response.2yeah so it is easy enough to solve in your head one liter of water, 3 liters of juice makes 75% juice but i guess you still have to come up with an equation that they like

Best ResponseYou've already chosen the best response.2lets see if we can do that, even though it is not necessary to write an equation to solve this rather simple question

Best ResponseYou've already chosen the best response.2we can call the number of liters of juice \(j\) if you like, since that is what you have to find

misty1212

Best ResponseYou've already chosen the best response.2that means \[j+1\] is the total amount right?

misty1212

Best ResponseYou've already chosen the best response.2and since it has to be \(75\%\) juice we also know \(j\) must equal it must be \(.75(J+1)\)

misty1212

Best ResponseYou've already chosen the best response.2set \[j=.75(j+1)\] and solve for \(j\)

misty1212

Best ResponseYou've already chosen the best response.2you will get \(j=3\) when you solve that, just like you knew at the beginning without resorting to this rather silly equation

Best ResponseYou've already chosen the best response.0Oh ok. So that's the equation?

misty1212

Best ResponseYou've already chosen the best response.2that is one you can use, yes and it does only have one variable

misty1212

Best ResponseYou've already chosen the best response.2solve \[j=0.75(j+1)\] and you will get \(j=3\) as the solution

Best ResponseYou've already chosen the best response.0And just to make sure this would be part B? j = .75(j + 1) j = .75j + .75 j  .75j =.75 0.25j = .75 j = 3
