Answer:

$\mathrm{A.\: 50^{\circ} }$

Step-by-step explanation:

Since there are 360 degrees in a circle, we can set up the following proportion:

$\frac{50}{360}=\frac{x}{360},\\360x=50\cdot 360,\\x=\boxed{50}$

First add the prices of the original books.

2.5+4.95+6=11.45

Find 20% of 11.45

=2.29

Therefore I saved $2.29
