"Kylie picked one-seventh of a basket of apples yesterday. She picked one-half of a basket of apples today. What part of a basket of apples has Kylie picked all together?"

Does this mean that Kylie picked one-seventh yesterday and picked one-half from the remaining six-seventh of the basket?
Mathematically: (1/7) + ((1/2)(6/7)) = 4/7 basket

OR does this mean that Kylie picked one-seventh of a whole basket yesterday and one-half from a DIFFERENT whole basket of apples today?
Mathematically: (1/7) + (1/2) = 9/14 basket

Thank you!
