Part a.
The drive had some files before the transfer. We don't know the number of megabytes already on the drive, so we call it x. x is the number of megabytes on the flash drive before Agent Hunt started the transfer.
He transferred files at a rate of 4.4 megabytes per second for 32 seconds. That gives a total of 4.4 Mb/sec * 32 sec = 140.8 transferred megabytes.
He ended up with 384 megabytes.
x + 140.8 = 384
Now we can solve for x, the number of megabytes originally on the flash drive.
x = 384 - 140.8
x = 243.2
The flash drive has 243.2 megabytes when the transfer began.
Part a. Answer: 243.2 megabytes
Part b.
The total capacity if the flash drive is 1000 megabytes. He already had 243.2 megabytes on it before this transfer. 1000 Mb - 243.2 Mb = 756.8 megabytes
The flash drive has capacity for an additional 756.8 megabytes when he started the transfer. The rate of transfer is 4.4 megabytes/second.
756.8/4.4 = 172
Part b. Answer: 172 seconds
