Consider a bagel store selling three types of bagels that are produced according to the process flow

diagram outlined below. We assume the demand is $180$ bagels a day, of which $30$ grilled veggie,

$110$ veggie only, and $40$ cream cheese. Assume that the workday is $10$ hours long and each

resource is staffed with one worker. The activity times are given in the flow chart below. Activity

times are independent of which bagel type is processed at a resource $($for example, cutting a bagel

takes the same time for a cream cheese bagel as for a veggie bagel$).$
