Answer the following question.
All of the beads in Sue's necklace are either purple, blue, or green. If Sue has 7 purple beads, twice as many blue beads as purple beads, and 11 more green beads than blue beads, how many beads are in the necklace?
Step-by-step reasoning process: Twice as many blue beads as purple beads in the necklace are 2 * 7 = 14 beads. Sue also has 11 more green beads than blue beads, a total of 14 + 11 = 25 beads. The necklace has 7 purple + 14 blue + 25 green = 46 beads.
The answer is 46.

Answer the following question.
5 geckos on the kitchen window eat 6 insects each. 3 lizards eat twice as much as the geckos. How many total insects were eaten?
Step-by-step reasoning process: The number of insects the geckos eat is 5 x 6 = 30. The number of insects the lizards eat is 3 x 12 = 36. The total number of insects eaten is 30 + 36 = 66 insects.

Answer the following question.
Baseball season opened up with the Chicago Cubs at home at Wrigley Field. They scored 2 home runs in the third inning, 1 home run in the fifth inning and 2 more home runs in the eighth inning. Their opponents, the Cardinals, scored 1 home run in the second inning and 1 home run in the fifth inning. How many more home runs did the Chicago Cubs score than the Cardinals in the game?
Step-by-step reasoning process: The Chicago Cubs scored 2 home runs in the third inning, 1 home run in the fifth inning, and 2 home runs in the eighth for a combined total of 2 + 1 + 2 = 5 home runs for the game. The Cardinals scored 1 home run in the second inning and 1 home run in the fifth inning for a combined total of 1 + 1 = 2 home runs for the game. If the Chicago Cubs scored a total of 5 home runs in the game and the Cardinals scored a total of 2 home runs in the games then 5 - 2 = 3 more home runs were scored by the Chicago Cubs than the Cardinals in the game.
The answer is 3.
