Q: 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?
A: 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. The answer is 504.
