Final answer:
The question asks for the percent of Lisa's friends that attended her wedding, but does not provide enough information to calculate a percentage. Mathematical formulas involving percentages cannot be used without specific numbers of attendees and friends.
Step-by-step explanation:
To determine what percent of Lisa's friends attended her wedding, we would need specific numbers pertaining to Lisa's friends and attendees, neither of which are provided in the question. However, the information about graduating students and their attendance at graduation does not relate directly to Lisa's wedding. Therefore, we cannot answer this question with the provided information.
In a mathematical context to solve such a problem, you would typically use the formula:
Percentage attended = (Number of friends who attended / Total number of friends) × 100%
Without the actual numbers of attendees and total friends, we're unable to calculate the exact percentage for Lisa's wedding.
