In a video game, players earn points for completing different types of quests. A player earns $10$ points for a 'basic' quest and $25$ points for an 'advanced' quest. If $B$ represents the number of basic quests completed and $A$ represents the number of advanced quests completed, the total points earned, $P$, can be represented by the equation $P=10B+25A$. How many times greater is the point value of an advanced quest than a basic quest?
