Context: In my IELTS class, I have to rewrite this sentence using a different structure:
There will be a sharp increase in the use of computers in classroom by the next decade.
My answer was:
By the next decade, computer usage in classroom will grow tremendously.
and the Answer Key was:
Classroom computer use will increase sharply by the next decade.
Did I use the word 'usage' correctly? Does my answer sound right and natural with you native speakers? Can 'use' and 'usage' be used interchangeably in this case?
I have looked up the 2 words in dictionaries and read this link as a reference but I still can't really tell what's right or wrong: https://english.stackexchange.com/questions/34712/use-vs-usage/34714#34714
Thank you!
