Tree pruning company A charges a one-time $100 equipment fee and charges $50 for each tree that it prunes. Tree pruning company
kobusy [5.1K]
The total cost that a customer should incur in its dealings with company A should be, 
                              c = 50t + 100
For company B
                              c = 60t + 80
Equating these two charges
                               c = 50t + 100 = 60t + 80
Thus, the answer is the fourth choice.
