Sandra Robinson recently opened her own basket$-$weaving studio. She sells finished baskets in addition to the raw materials needed by

customers to weave baskets of their own. Sandra has put together a variety of raw material kits, with each kit including materials at

various stages of completion. Unfortunately, because of space limitations$,$ Sandra is unable to carry all the varieties of kits she

originally assembled and must choose between two basic packages.

The basic introductory kit includes undyed, uncut reeds $($with dye included$)$ for weaving one basket. This basic package costs Sandra

$$14$ and sells for $$28.$ The second kit, called Stage $2,$ includes cut reeds that have already been dyed. With this kit, the customer only

has to soak the reeds and weave the basket. Sandra is able to produce the second kit by using the basic materials included in the first

kit and adding one$-$half hour of her own time, which she values at $$20$ per hour. The kit of dyed and cut reeds sells for $$35.$

Determine whether Sandra's basket$-$weaving shop should carry the basic introductory kit with undyed and uncut reeds or the Stage $2$

kit with reeds already dyed and cut.
