    If we let x be cans, then let y represent bottles

    hence the total weight would be the weight of how many bottles she has + the weight of how many cans she has

    because 1 bottles weighs 17ounces (i.e when x=1... and so on)

    so how much would 2 cans weigh (i.e x=2)...it would be 14*2=28ounces right?

    so x cans would weigh 14x and y bottles would weigh 70y

    hence, total weight = 14x+70y if we combine the bottles and cans right?

    good so we also know that x+y=950 (no. of cans and bottles) and total weight=14x+70y

    seems here we aren't told how many bottles and cans of each there are, only that there are 950 cans and bottles together

    because if i said i was holding two cans, that means x=2 which also means 2 cans weighs, 14x=14*x=28 ounces

    that irrelevent to be honest, our expression is simply: Total weight = 14x+70y

    it seems that 950 cans and bottles is redundant for the total weight expression unless we know how many cans and bottles there are
