which sentence is written correctly? mike, has lost 40 pounds, because he started eating healthy and running each day. maggie broke her leg, while jumping into the pool, and has to wear a cast for eight weeks. snow cones, a tasty treat, can be found in many delicious flavors. the musicians, performed their hit songs, at the weekend concert.

Explanation:

1. Analyze the first sentence: "Mike, has lost 40 pounds, because he started eating healthy and running each day." - The comma after "Mike" is incorrect as the non - restrictive clause "has lost 40 pounds" is mispunctuated. It should be "Mike has lost 40 pounds because he started eating healthy and running each day." or with correct non - restrictive punctuation like "Mike, who has lost 40 pounds, started eating healthy and running each day."
2. Analyze the second sentence: "Maggie broke her leg, while jumping into the pool, and has to wear a cast for eight weeks." - The commas around "while jumping into the pool" are incorrect. The phrase "while jumping into the pool" is an adverbial clause and does not need to be set off with commas in this way. It should be "Maggie broke her leg while jumping into the pool and has to wear a cast for eight weeks."
3. Analyze the third sentence: "Snow cones, a tasty treat, can be found in many delicious flavors." - This sentence is correctly punctuated. The phrase "a tasty treat" is a non - restrictive appositive that is properly set off with commas.
4. Analyze the fourth sentence: "The musicians, performed their hit songs, at the weekend concert." - The commas around "performed their hit songs" are incorrect. The verb phrase "performed their hit songs" is the main predicate of the sentence and should not be set off with commas. It should be "The musicians performed their hit songs at the weekend concert."

Answer:

Snow cones, a tasty treat, can be found in many delicious flavors.
