Tree pruning company A charges a one-time $100 equipment fee and charges $50 for each tree that it prunes. Tree pruning company B charges a one-time $80 equipment fee and charges $60 for each tree that it prunes.
Let the variable t represent the number of trees pruned and let the variable c represent the cost. For how many pruned trees will the cost be the same for both companies?
Which system of equations can be used to solve this problem?
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.
