Lizzy: Keith and Blaine went fishing. Blaine caught 5 fish while Keith caught twice as many as Blaine's. How many fish did they catch together?.
Me: Hmmm, let me think. I think this is the detailed solution:
Keith caught 5 x 2 = 10 fish. Therefore, they caught a total of 5 + 10 = 15 fish. Final answer: 15.
