Economy Movers charge $85 plus $40 an hour to move households across town. Helpful Moving Company charges $60 an hour for crosstown moves. For what lengths of time is Helpful Moving Company more expensive?

I'm sure there's an algebraic method of determining this.
However, trial and error will also get the answer.
85 + 40 = 125
85 + 80 = 165
85 + 120 = 205
85 + 160 = 245
60
120
180
240 
A= Total charges of Economy Movers in t hours.
B= Total charges of Helpful Moving Company in t hours.
Write an inequality B>A to determine t.
