Best ResponseYou've already chosen the best response.0Right. So since she spent put 2/3 in the savings account, that means we have 1/3 of the total right now at 61. So what will we multiply the 61 by to get the total?

Best ResponseYou've already chosen the best response.0Here, I'll write in equation form to make it a little easier. \[\frac{ 1 }{ 3 }*x=1\] What would x be?
