###Human: Bella eats 6 apples a day. If during the week she consumes a third of the apples Grace picks, how many apples will Grace have after 6 weeks?, ### Assistant: Bella eats during the week, 6 apples/day * 7 days/week = 42 apples/week
Grace harvests 42 apples/week * 3 = 126 apples during the week.
Leftover after Bella eats, 126 apples/week - 42 apples/week = 84 apples/week.
After 6 weeks Grace will have 84 apples/week * 6 weeks = 504 apples. 
 So the answer is :  504
