Question 237120

 
a. Set up a system of equations to describe this situation. (3 points)
   {3.35x+2.60y=20850}
   {    x+y = 7500   }  
b. Solve the system of equations to find the solution. (3 points)
   3.35(1800) + 2.60(5700) = 20850
    6030+ 14820 = 20850
      20850 = 20850
______________________________
      1800+5700= 7500
         7500= 7500
