Question 188866
a) Option 1: {{{C=32+3*x}}}
   Option 2: {{{C=6.5*x}}}

b) {{{(32+3*x)<(6.5*x)}}}
   
   Subtract 3*x from both sides

   {{{32<3.5*x}}}
  
   Divide both sides by 3.5

   {{{9.143<x}}}

   This means that you have to rent the court for more than 9.143 hours so that Option 1 payment option is less than Option 2
