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).
Think hard. Detailed solution:
400
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.

.

Final answer: 400
