Algebra.Com's Answer #848962 by CPhill(1959)![]() ![]() You can put this solution on YOUR website! **1. Calculate the maximum number of students potentially in the reading room at any given time:**\r \n" ); document.write( "\n" ); document.write( "* **Total student-hours:** 267 students * 5.625 hours/student = 1503.125 student-hours \n" ); document.write( "* **Maximum concurrent students:** 1503.125 student-hours / 8 library hours = 187.89 students \n" ); document.write( "* **Round up:** 188 students (since we can't have a fraction of a student)\r \n" ); document.write( "\n" ); document.write( "**2. Calculate the number of seats needed to accommodate at least 78% of students:**\r \n" ); document.write( "\n" ); document.write( "* **Seats required:** 188 students / 0.78 = 241.03 students \n" ); document.write( "* **Round up:** 242 seats\r \n" ); document.write( "\n" ); document.write( "**Therefore, the reading room should have at least 242 seats to ensure that at least 78% of students can find a free spot.**\r \n" ); document.write( "\n" ); document.write( "**Note:** This calculation assumes a uniform distribution of student library usage throughout the day. In reality, there may be peak times with higher student traffic, which would require a more robust analysis and potentially more seats. \n" ); document.write( " \n" ); document.write( " |
