Consider a sequential process with $3$ stations. The processing time $($minutes per unit by $1$ employee$)$ and number of employees at each station are as follows:

Processing time

Station A: $6mi\frac{n}{?}$ unit

Station B: $2mi\frac{n}{?}$ unit

Station C: $6mi\frac{n}{?}$ unit

Number of Employees

$3$ employees

$4$ employees

$6$ employees

If demand rate is$.20$ units per hour, what is the utilization of Station A rounded $to$ the ${?}_{(})$ nearest percent?

$100\%$

$67\%$

$50\%$

$33\%$
