| You collect coins. Suppose you start out with 11. Since
his mother makes coins, Miguel decides to double your coins. Since
you're nice, you give Mary 12 coins. How many coins do you have at the
end? Solution: The given word problem is about the application of four basic operations. At the start, you have 11 coins. If Miguel doubles the number of coins you have, then you have 11 x 2 = 22 coins. Since you're nice, then you give 12 coins to Mary. Therefore, you have 22 - 12 = 10 coins left at the end. |
