A restaurant that provides an Entr$$e $($Food Station $1)$ Station, Grill $($Food Station $2)$ Station, and Pizza

$($Food Station $3)$ station. Lunch lasts for $2$ hours, from $11$:$30am$ to $1$:$30pm.$ About $400$ students come to

take food during the two hours of lunch. Let us assume it is exactly $400$ students over $2$ hours, but it

varies over those two hours, and it also varies from station to station. Each student comes and orders

exactly one meal from one of the stations. After students take their food from any of these stations, they

line up to pay at the pay stations. Any extra food remaining at the end of the lunch hour is donated to a

local charity.

Station $3$:

During regular class days, the demand for the station $3$ is the rest of the demand $($that is$,$ total demand

minus the demand for Entree and Grill$).$

The station $3$ is pizza takes no direct labor to serve, since the students serve themselves, but it takes $15$

minutes to bake a station $3$ item $($assume that the oven is large enough$).$ The food costs $$1($including

labor$),$ and is sold for $$3\mathrm{.}2$ per slice.

On average, how many station $3$ items $($not slices$)$ are baking in the oven?

On average how many slices of pizza are on display during lunch time?
