I may be wrong but if each of the four rooms required two cans, 4x2 is 8. then it says you spilt half a can, making that 8.5 cans. but, you have 1.5 cans left. 8.5+1.5= 10. 
 
        
             
        
        
        
Answer:


Step-by-step explanation:
Completing the square is a method of rewriting a quadratic equation in the standard form such that it is in vertex form. The first step is to group the linear and quadratic terms, then factor out the coefficient of the quadratic term. After doing so, complete the square, add a value such that the linear and quadratic terms form a perfect square trinomial. Do not forget to balance the equation. The final step is to simplify. 

Group,

Complete the square,

Simplify,

Now solve the equation using inverse operations,

 
        
             
        
        
        
     17(k + 6) > 3(5k + 4)
17(k) + 17(6) > 3(5k) + 3(4)
    17k + 102 > 15k + 12
  - 17k           - 15k
      2k + 102 > 12
            - 102 - 102
                2k > -90
                 2       2
                   k > -45
