Jeff has 16 GB of storage on his phone. He is already using 4 GB. If a song takes up about 30MB of storage, how many songs can Jeff store on his phone? (There are 1000 MB in a GB).
Thoughts? Step-by-step reasoning:
Jeff has 16 - 4 = 12GB left over on his phone. Therefore, he has 12 * 1000 = 12,000MB. Therefore, he can store 12,000 / 30 = 400 songs.
Thus, the answer is 400.
