if a caterer charges a fixed cost for preparing a dinner plus an additional cost for each person served and you know that the cost will be for 100 students will be $750 and the cost for 150 students will be $1050,what would the caterer's fixed cost and the cost per student be?(using linear equations)
\n" ); document.write( "------
\n" ); document.write( "You have two points relating # of students and cost
\n" ); document.write( "(100,750) and (150,1050)
\n" ); document.write( "---
\n" ); document.write( "slope = (1050-750)/(150-100) = 300/50 = 6
\n" ); document.write( "---
\n" ); document.write( "Form: c = mx + b
\n" ); document.write( "750 = 6*100 + b
\n" ); document.write( "b = 150
\n" ); document.write( "----
\n" ); document.write( "Cost(x) = 6x + 150
\n" ); document.write( "---
\n" ); document.write( "Cost per student = $6
