The instruction says that we should rewrite this sentence, placing commas where they are needed. The rewritten sentence has been shown below:

  • We are excited to announce that our town is going to build a new middle school. The building will have comfortable, spacious classrooms, with huge glass windows. The hallways will be long, wide, and colorful. The walls will have unique, vibrant murals painted by talented student artists. There will be modern science labs and a large indoor auditorium. It will be a welcoming, bright, and fun place to learn and grow.

Commas are important punctuation marks that are used in separating items in a list.

They prevent confusion during readings by properly grouping items. In the text above, commas were used to separate the items in a list.

For example, in the third sentence, commas were used to separate the adjectives that qualify the hallways.

In conclusion, commas were used to correctly separate words in the excerpt above.

How much change should you get from a ten dollar bill if you buy items for $3.69 each?
Aleksandr [31]
First find out how many things you can buy. $3.69 + $3.69 is $7.38. If you add one more item that is $3.69 that would be over $10, so you can only buy two things. If you take the price of your two items ($7.38) minus $10.00, what is your answer?
