$50.67 +Explanation
Step-by-step explanation:
I am assuming that the "algorithms" are the equations and ways that can be used to go about and solve the problem, and there are two to chose from. The mathematics themselves are quite simple; either add the cost of each book together nine times for the nine books she bought, or, for a quicker, easier way, multiply $5.63 by 9. Either way, the answer will be $50.67.
