With Funding from Her Family, Sarine Is Currently Developing a New

With funding from her family, Sarine is currently developing a new line of dolls for her business, which she hopes will take her company to the next level. At first, she encountered some minor problems with the construction of the dolls and spent a fair amount of money engineering a way to enable them to be as she envisioned them to be. Unfortunately, she then found out that there was a patent protecting the way the dolls arms were connected, so she spent more money redesigning the dolls. After an unexpectedly uninterested response from the public in the dolls, she decided that they needed to be marketed differently in order to sell. With this in mind, Sarine allocated more resources to marketing, had the packaging of the dolls redesigned, and created a new set of advertising materials. The cost of manufacturing these dolls has now exceeded the initial proposed cost by four times, but she is determined to make it work. She is embarrassed by how this has gone but continues to put on a brave front.
