Continuous Flow versus Departmental Flow Manufacturing

Bienestar Inc., has the following departmental structure for producing a well$-$known multivitamin:

A consultant designed the following cellular manufacturing structure for the same product:

The times above the processes represent the time required to process one unit of product.

All answers should be in "minutes"

$1.$ Calculate the time required to produce a batch of $15$ bottles using a batch$-$processing departmental structure.

$2.$ Calculate the time to process $15$ units using cellular manufactoring. Assume that the cell is not continuously producing.

$3.$ How much manufactoring time will the cellular manufactoring structure save for a batch of $15$ units? Assume that the cell is not continuously producing. Round to answer to two decimal places.

PLEASE DOUBLE CHECK ALL WORK! Will give a thumbs down if all parts are not done correctly! Thanks!
