Question

Please put this into an equation problem= Chuck has 8.25 gigabytes on his hard drive. Chuck wants to load 3 movies in the drive that take up 3.6,2.8, and 4.1 gigabytes each. To make room for the movies, Chuck plans to delete a 2.3 gigabyte movie. Does Chuck have enough space for 3 new movies?
Steve
the 3 movies use 3.6+2.8+4.1 = 10.5 GB

So, his available space will be 8.25+2.3 = 10.55 GB
