Step-by-step explanation:
diagonals bisect
5u-10= 2u+2
3u = 12
u=4
v/3 = 6
v=18
 
        
             
        
        
        
You have two choices.
The minimum possible cost to operate your bat factory for a day is $390,
and there are two quantities of bats that both cost that much.
One possibility:  
                   Produce no bats at all per day.  Zero.  Nada.  None. 
                    Cost = 0.06(0)²  -  7.2(0)  +  390  =  $390 per day.
The other choice:
                   Produce  120 bats per day.
                   Cost = 0.06(120²)  -  7.2(120)  +  390
                          = 0.06(14,400)  -  7.2(120)  +  390
                          =      864          -      864      +  390
                          =      $390  per day.
If you produce any other number of bats in a day ... more than zero 
but not 120 ... then it will cost you more than $390 to operate the factory 
that day.
