Question $17$

A fabric cutting machine processes the cutting task. The fabrics need to be layered prior to each cutting task, and it takes

$10$ seconds to lay out one piece of fabric. After the fabrics are layered, the cutting begins, which takes on average $2\mathrm{.}5$

minutes for each batch. The batch size for each cutting task $10$ layers$/$batch$.$ Given this operating process, what is the

capacity of the cutting machine $($in layers per minute$)($round to one decimal place$)?$
