Cecile buys a move to watch on her phone, but she’s worried about the amount of storage space downloading it will take up. She starts the download and notices it will download at a constant rate. After 3 minutes, she checks her phone and sees that she has 2,345 MB (megabytes) of space available. She checks her phone after 7 minutes and notices that she now has 2,105 MB of space available.
a. How many MB of available storage are being filled by the movie per minute? b. How much space was available on her phone before the download started? c. Suppose the download lasted for a total of 19 minutes. How much available storage remains after downloading the movie?
