$\bf \textit{area of a triangle}\\\\ A=\cfrac{1}{2}bh~~ \begin{cases} b=base\\ h=height\\ \cline{1-1} A=56 \end{cases}\implies 56=\cfrac{1}{2}bh\implies 112=bh \\\\\\ \boxed{112=2\cdot 2\cdot 2\cdot 2\cdot 7}\to \begin{cases} 16\cdot 7\\ 8\cdot 14\\ 4\cdot 28\\ 2\cdot 56 \end{cases}\qquad or\qquad \begin{cases} 7 \cdot 16\\ 14 \cdot 8\\ 28 \cdot 4\\ 56 \cdot 2 \end{cases}$

so their product is 112, so tis just a matter of doing some quick prime factoring and combining the factors about.

For this case we will first look for the total cost of the purse.
We then have the following rule of three:
14.95 $ > 100%
x > 105%
Clearing x we have:
x = (105/100) * (14.95)
x = 15.6975 $
The amount needed to buy the purse is:
15.6975 - 10 = 5.6975 $

holley needs 5.6975 $ to buy the purse
