Question 1115801: The Warbler House Inn offers two plans for wedding parties. Under plan​ A, the inn charges ​$30 for each person in attendance. Under plan​ B, the inn charges ​$1400 plus ​$15 for each person in excess of the first 35 who attend. For what size parties will plan B cost​ less? (Assume that more than 35 guests will​ attend.)

Plan A: 30x
Plan B: 1400 + 15(x-35)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
30x < 1400 + 15x - 525
15x < 875
x = 58.33 NOTE: you can't split a person, so at 58 guests and under, Plan A is cheaper. At 59 guests and up, plan B is cheaper.
