Assume a TCP sender is continuously sending 1,047-byte segments. If a TCP receiver advertises a window size of 8,498 bytes, and with a link transmission rate 14 Mbps an end-to-end propagation delay of 14.9 ms, what is the utilization?

Assume no errors, no processing or queueing delay, and ACKs transmit instantly. Also assume the sender will not transmit a non-full segment.

Give answer in percentages, rounded to one decimal place, without units (e.g. for an answer of 10.43% you would enter "10.4" without the quotes).
