2. Tree pruning company A charges a one-time $85 equipment fee and charges $60 for each tree that it prunes. Tree pruning company B charges a one-time $65 equipment fee and charges $70 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?

{c=85+60tc=65+70t
left curly bracket. First line. c equals 85 plus 60 t. Second line. c equals 65 plus 70 t

{c=85t+60c=65t+70
{c=145tc=135t
{c=85−60tc=65−70t
