Suppose you have a three task seq go to Task $D$ before leaving. No buffers exist between tasks, so blocking$/$starvation rules apply.

Suppose throughput capacities are as follows. Task A: $10$ customers$/$hour; task B: $5$ customers$/$hour; task C: $6$ customers$/$hour; task D$,9$ custor

At what rate will customers leave task D $($in customers$/$hour$)?$ Assume the $25\frac{\%}{75}\%$ split between tasks B & C must always be upheld.

Pick the closest answer.

$5$

$6$

$7$

$8$

$9$

$10$
