Problem of the Week - Lower Elementary - Jan. 10, 2021 to Jan. 16, 2021

Lower Elementary: 

Question: A shark eats 10 fish on Monday, 9 fish on Tuesday, 8 fish on Wednesday, and so on. If the pattern continues, how many fish does the shark eat over the course of 1 whole week?

Answer: 49 fish

Solution: The pattern is that the shark eats one fewer fish each day. So, since there are 7 days in a week, the shark eats 10 + 9 + 8 + 7 + 6 + 5 + 4 = 49 fish.
